If your right were taken away unfairly, what would be your reaction? Of course, you would stand up for your right and try to take it back or maybe fight for it. What if this reaction would make everything worse? What if you realize that your compromise, leads into the greater good of yourself or even the society? Fighting against injustice, sometimes, includes sacrifices, which goes beyond egotistic and individual desires. Depending on the situation, one might be made to compromise and sacrifice his/her right for the sake of his/her higher purpose, while having the power to take his/her right back. And this can only be done by a spiritually and mentally powerful person, such as Imam Hasan al-Mujtaba (AS), the first grandson of Prophet Muhammad (PBUH&HP). 

In what follows, we will review the life of this exceptional figure in the history of Islam. 

Birth and Lineage

Hasan ibn Ali (AS), known as Hasan al-Mujtaba (AS), was born on 15th of Ramadan, 1st of March, 625 A.D. in Medina. He was the first son of Imam Ali (AS) and Lady Fatima (AS), and the first grandson of Prophet Muhammad (PBUH&HP). His name, "Hasan," which means good or beautiful, and was chosen by his grandfather, the Prophet (PBUH&HP), for him, having no precedent in this name in the pre-Islamic history. 

Imam Hasan (AS) and Prophet Muhammad (PBUH&HP)

Imam Hasan (AS) was only seven years old when Prophet Muhammad (PBUH&HP) passed away. Prophet Muhammad (PBUH&HP) dearly loved him, and as it is narrated, he used to put Imam Hasan (AS) on his shoulders and said, "O' Allah! I love him, therefore, You love him, too." [1] In some instances, while Prophet Muhammad (PBUH&HP) was performing the congregational prayer in the mosque, Imam Hasan (AS), then a little boy, would go on Prophet Muhammad's (PBUH&HP) back while he was prostrating. In response, Prophet Muhammad (PBUH&HP) would kindly and patiently prolong his prostration, so that he would come down himself. Prophet Muhammad's (PBUH&HP) manner of treating his grandsons was, in fact, a model to his followers to treat their children respectfully and compassionately. 

His love and respect toward Imam Hasan (AS) are evident through the many narrations left by him about his grandson: "Surely, Hasan and Hussain are my two fragrant flowers from this world; he who loves me, should love them, too" [2], "Hasan is my son and dear to my heart, whoever hurt him, is like he's hurting me" [3], "Hasan and Hussain are the masters of the youth in paradise" [4]. It has also been narrated that Imam Hasan (AS) very much looked like Prophet Muhammad (PBUH&HP) in both appearance and personality [5]. Despite his young age, Imam Hasan (AS) was present in many significant incidents in Prophet Muhammad's (PBUH&HP) time.

The Short Period of Imam Hasan (AS)'s Caliphate 

After Imam Ali's (AS) tragic martyrdom in 661 A.D, many people in Iraq and the neighboring lands pledged allegiance to Imam Hasan (AS), as the most suitable person to be their Caliph succeeded by Imam Ali (AS). Nevertheless, soon after this pledge of allegiance, Mu'awiya b. Abi Sufyan [i] refused to respect people's choice and offended Imam Hasan's (AS) caliphate. He tried to incite people of Iraq by sending two spies who were captured and punished by Imam Hasan (AS) [6]. Finally, Mu'awiya provoked a rebellion in Syria against Imam Hasan (AS) and built an army to go into war with Imam (AS) in Iraq. It is reported that 60,000 soldiers or more accompanied Mu'awiya [7].

In this situation, Imam Hasan (AS) gathered an army of Kufa people to fight against them and defend the people. Some minor battles occurred between the two troops. Later, Imam Hasan (AS) joined the army of Kufa and gave a sermon to them, inviting them to unity and reconciliation rather than hatred and enmity. After this speech, people thought that Imam (AS) was after making peace with Mu'awiya and accused him of disbelief, attacked his tent, and left his side. Also, some of the heads of Imam Hasan's (AS) army, including "Ubayd Allah b. 'Abbas", the commander in chief of Imam Hasan's (AS) army, joined Mu'awiya's army with two-third of his army.  Before that, Mu'awiya had sent them letters and promised them high positions in his government and a considerable amount of money. This was followed by the letters of the chiefs of Iraqi tribes to Mu'awiya, expressing him their support.

All these incidents resulted in the significant physical weakening of Imam Hasan's (AS) army and losing their spirit, despite Imam Hasan's (AS) efforts to give them heart through his influential and alarming speeches. Yet the covert activities of Mu'awiya in Kufa, sending his forces undercover among people and spreading false accusations concerning Imam Hasan (AS), gradually broken Imam Hasan's (AS) army. Some even assassinated Imam Hasan (AS) and wounded him severely. 

Finally, pressing hard under the conspiracies of Mu'awiya and the weakness of people in fighting against injustice, which had disturbed the military balance between the two armies, Imam Hasan (AS) was made to accept a peace treaty and leave the caliphate to Mu'awiya [8]. Thus, the period of Imam Hasan's (AS) caliphate lasted between six to eight months.

The Peace Treaty between Imam Hasan (AS) and Mu'awiya 

According to historical accounts, "Mu'awiya sent a blank contract with his seal at the bottom for Imam al-Hasan (a) to write anything that he wished and thus he wrote, "In this peace treaty, al-Hasan b. 'Ali (a) establishes peace with Mu'awiya b. Abi Sufyan and leaves the government of the Muslims to him with the following conditions:

1. He observes the Book of God, the conduct of the Prophet (s), and the conduct of the righteous caliphs.
2. He appoints no one as the Caliph after himself; and after him, the Caliph should be elected by a council of Muslims.
3. Lives, property, and children of people should be safe everywhere.
4. Mu'awiya should not implicitly or explicitly plot against al-Hasan b. 'Ali or threaten any of his companions." [9] 

Under these conditions, Imam Hasan (AS) signed the peace treaty in 661 A.D. However, all of these conditions were later denied by Mu'awiya in his sermons and manners. "After the peace treaty, Imam (AS) gave a sermon and pointed to this issue that Mu'awiya challenged him over his rights and explained the reasons for his peace, which was to protect the lives of people and avoid bloodshed. After the treaty, Mu'awiya, too, gave a sermon at his first presence in Kufa. He broke his promises, saying that Imam (AS) had asked for peace and cursed Imam Ali (AS). Then, Imam Hasan (AS) explained about the peace treaty in a sermon and the proposal of Mu'awiya for it and answered to Mu'awiya's disrespect to his father." [10]

After this incident, Imam Hasan (AS) went back to Medina. While he was not a caliph anymore, he felt the responsibility to guide people in religion, science, and social and political issues. The signing of the peace treaty had made the situation very difficult for him. Some people criticized him, some of his old companions left his side, and severe political measures were taken against him. 

Imam Hasan (AS)'s Prominent Characteristics

Forbearance and Patience 

Imam Hasan's (AS) patience in the face of hardship becomes evident by having a glance at his life, which was full of challenges. Losing Prophet Muhammad (PBUH&HP) when he was only a child, losing his mother, lady Fatima (AS), bearing the difficulties at the time of his father's caliphate, following by his martyrdom most brutally, electing as a caliph by the people and then being abandoned by the same ones provoked by Mu'awiya, being forced to accept a peace treaty and giving up caliphate unfairly, was only some of these hardships. No doubt, without a strong personality resulted from a deep belief in Allah, Imam Hasan (AS) would not be able to bear these sufferings and challenges. 

Moreover, he presented forbearance even when he was directly insulted and never responded with anger. In an instance, "a Syrian man saw Imam Hasan (AS) and started cursing him. When he finished his insults, the Imam (AS) smiled, greeted him, and said, "It looks like you are a stranger in this city … If you need anything, we will fulfill your needs." The man was deeply impressed by the Imam's (AS) noble reaction; he started crying and recited the following verse: "God knows best with whom to place His message" (Quran 6:124), indicating that the Imam (AS) deserved to be a descendant of the Prophet (PBUH&HP)" [11]. 

Generosity 

Imam Hasan's (AS) life was full of instances, which revealed his immense generosity and selflessness. It is narrated that he had given away all his properties and wealth as a charity twice in his lifetime [12]. According to an account, a man in need came to Imam Hasan (AS). Imam (AS) asked him to write what he needed and give him the note. When Imam (AS) read his letter, he gave him twice more than what he had asked. One of the people who were present there said, "What a bounteous letter he wrote, O' son of the Prophet (PBUH&HP)!" Imam (AS) replied, "The letter had more bounty and blessing for us than him since it had made us among the generous ones. Don't you know that "generosity" is to give something to someone without being asked for, and what is given away after being asked, is paltry in return to that person's honor.  Perhaps the one who asked for something had spent a night full of stress and fear, not knowing if you reject him or make him happy with accepting to fulfill his request. Now he has come to you, his heart beating fearfully. If you, then, give him no more than what he had asked, you don't give away anything worthier than his honor, which he had broken for this request." [13] 

Imam Hasan's (AS) generosity was not limited to human beings, but all of Allah's creatures. In one account, a man saw Imam Hasan (AS) eating, giving a morsel of his food to a dog, and eating a morsel himself. The man who was surprised by this scene went closer to Imam Hasan (AS) and said, "Would you permit me to hit this dog with a stone and take him away from your food?" Imam (AS) replied, "Leave it alone! Since I feel ashamed of Allah al-Mighty if an alive animal looks into my face while I'm eating and I won't give it part of my food." [14]  

Imam Hasan (AS) found generosity and doing charity, not as a mere religious burden; instead, he gave away willingly and saw it as a chance bestowed to him by Allah to please Him. 

Humbleness toward the Poor

The grandson of Prophet Muhammad (PBUH&HP), following the footsteps of his grandfather, was highly observant of his manner toward the ones in need, being careful not to break their hearts or belittling them while helping them. It is reported in an account, "One day, he passed by a group of poor people who were eating pieces of bread. When they saw him, they invited him to eat with them. The Imam (AS) accepted their invitation and sat and ate with them and then invited all of them to his house and offered them food and clothes." [15]

Imam Hasan (AS) never felt superior to other people and treated everyone, regardless of their age or position, with the same respect and modesty. 

His Love for Allah  

All the above characteristics of Imam Hasan (AS) and many more is a reflection of his deep devotion and love toward Allah, the One and Only Creator. Imam Hasan (AS) was the perfect example of a true believer both in manner and words. He was famous for his sincere worship, long prayers, and his enthusiasm to go on a pilgrimage to Mecca on foot. He would say, "I would be embarrassed to meet my Lord without having walked toward His house." [16] 

His abiding faith had made him a strong and exemplary personality from whom any human being with a free soul can learn the lesson of humanity and love.   

His Martyrdom

According to some historical sources, After disregarding the conditions in the peace treaty, Mu'awiya conspired the assassination of Imam Hasan (AS) to secure the position of his son, Yazid, as his successor. To further his plan, he sent for Imam Hasan's (AS) wife and enticed her to poison her husband in return for money and marrying Yazid. Finally, she accepted his offer and fatally poisoned Imam Hasan (AS) [17]. He was martyred in the 15th of Ramadan of 50 (670 A.D.) and was buried in al-Baqi' cemetery in Medina.

Imam Mahdi (AS) is the last and the twelfth Imam of the Shiite Muslims. He was born in 255 H (874 AC) and the Shiite Muslims believe that their last Imam has been alive for approximately 1150 years. According to Shiite narrations, Imam Mahdi (AS) is currently in occultation and hidden from the public.

In this regard, Imam Kazim (AS) says:

The apparent gift of Allah is an Imam known to the people and the Hidden gift of Him is an Imam who is hidden. 

After that, the narrator of this hadith asks the Imam: “Is there going to be a hidden Imam?” Imam Kazim (AS) replied:

Yes! He will be hidden from the eyes of the people but the hearts of the faithful will not forget him. (1)

Despite Imam Mahdi (AS) being in occultation, we have responsibilities and duties to fulfill during this period. His hidden state doesn’t imply that Shiite Muslims have nothing to do for their faith and religion.

In fact, the best way to maintain a strong connection with our Imam is by following his orders. The Shiite Imams have told us about the responsibilities we have during this special time and some of them are mentioned below:

Upholding our faith

During the occultation of the Imam, it is a time when people may lose faith in him. In this regard, Imam Sadiq (AS) said:

With Mahdi (AS), there will be a little number of Arabs.

Then the Imam was told “But there are so many Arabs now that have faith in this religion!” Imam Sadiq (AS) replied:

People will inevitably be tested and they will be differentiated from one another and many will fail this test. (2)

The Holy Prophet (PBUH & HP) once prayed:

O Allah! Show me my brothers, Show me my brothers.

The people around him asked “O Messenger of Allah! Aren’t we your brothers?”

He responded:

No! you are my companions. But my real brothers are those who live in the last times of this world. They believe in me while they haven’t seen me … keeping faith in those times, will be more difficult than cutting the thorns of a plant on a dark night or holding a burning wood in one’s hands. They are the lights in the darkness and Allah will save them from every catastrophic test of seduction. (3)

As you see, being a faithful person is easy during the occultation. Therefore, one of our responsibilities is to keep our belief in Islam during these times. 

Harith ibn Muqhairah (one of the followers of Imam Sadiq (AS)) says “Once I told Imam Sadiq (AS): ‘We are being told that the leader of this religion will be hidden one day. So, in those times, what should we do?’”

Imam Sadiq (AS) said:

Keep your very faith that you have now and do as you have been ordered before him, until the time that everything will be clear for you [the arrival of Imam Mahdi (AS)].(4)

Getting to know Imam Mahdi (AS) more

Understanding the message of our Imams and having knowledge about their attributes and role in this world is crucial in the Shiite view. This is one of the most significant duties of Shias during the occultation. In this regard Imam Sadiq (AS) advises one of his pupils named Fozail:

O Fozail! Get to know your Imam because if you know him, it will be the same for youwhether his arrival is soon or delayed and anyone who knows their Imam and then dies before his arrival is like one of his soldiers. (5)

Praying 

In the Islamic point of view, praying is one of the most effective ways to have our wishes fulfilled. We should call upon Allah when we need Him and ask him to solve our problems, trusting that He will answer our prayers. The holy Prophet (PBUH & HP) said:

Call upon Allah while being certain that He will answer. (6)

Living without a guide in this world is the most significant problem we have. Without our Imams, we Shias have no savor and our problems seem never-ending. In this regard, Imam Sadiq (AS) says: 
The problems of the Earth will not be finished except by an Imam. (7)

Therefore, one of the most important prayers we should make is for the return of Imam Mahdi (AS). The Shiite Imams have persuaded their followers to pray for the arrival of Imam Mahdi (AS). 

Imam Sadiq (AS) told one of his pupils named Humran about the attributes of the occultation time and advised him:

When you saw … that the world is highly favorable for the unfaithful people and the flag of the righteous people is hidden, be cautious and ask Allah to save you. (8)

Imam Sadiq (AS) also said:

You Shias will face doubts in the future and [during those times] you won’t see a right flag or a guiding Imam and no one will be saved in those times except for the ones who pray like a drowning person. 
Then the narrator of the hadith asks the Imam: “How can I pray like a drowning person?”

Imam Sadiq (AS) replied:

You should say: 

“یا اللّه یا رحمن یا رحیم یا مقلب القلوب ثبت قلوبنا علی دینک”

O Allah! O Rahman! O Rahim! O Controller of the hearts! Make my heart keep its faith in your religion. (9)

Imam Mahdi (AS) himself wrote to one of his followers:

Pray so much to Allah for my arrival because it resolves all your problems (10)

In addition to this fact that praying makes his arrival more likely to happen sooner, praying is also the best way to relate to Imam Mahdi (AS) and this way, we can make a good connection to him. In return, Imam Mahdi (AS) sees that you are always thinking about him and praying for his arrival. It is obvious that Imam Mahdi (AS) loves the ones who do not forget him and pray for him more than others. Due to this fact, Imam Mahdi (AS) will pray for us in return and clearly, the praying of an Imam surely will be answered by Allah. 

Don’t forget that it is so important for praying for the arrival Imam Mahdi (AS) to be in a group. You should get together with your family, friends or even the other people to pray for Imam Mahdi (AS).

Imam Sadiq (AS) said:

If four people gather and pray, they won’t leave each other until Allah answers their supplication (11)

He also said:

When something would bother my father (Imam Baqir), he would gather all the women and kids in the house and he would pray and they would say “Amen.” (12)

As you see, praying together as a group holds great important for it to be answered by Allah. Imagine the impact if all the Shiite Muslims united in praying for the arrival of Imam Mahdi (AS) pure hearts. It is obvious that his occultation wouldn’t have prolonged for so long. So, one of our important responsibilities toward Imam Mahdi (AS) is to encourage others to pray for his arrival and we’d better pray in group. 

There are many other responsibilities we have during the occultation. The most important thing is to follow the orders of the previous Imams and fulfill all of our religious obligations so that Allah would save us from this dangerous time.
