There is a question that occupies the minds of many of us; what will remain of us in this world after we are long gone? Have we left this world and the generations followed by us a worthy legacy? Or we will soon be forgotten? Or even worse, we have left so much evilness and destruction that would never be wiped away from the face of this world? Looking at the lives of prominent figures, throughout the history of Islam, we realize how much effort they have put into spreading a valuable message and leaving behind an enduring legacy for future generations. Despite being under the restraint and pressure of the Caliphs of his time, Imam Sadiq (AS), the sixth Imam of Shias and one of Prophet Muhammad's (PBUH&HP) grandchildren, has left Muslims with the most considerable amount of religious content which turned into an essential point of reference for them until the present.

In what follows, we will have a look at the life of Imam Sadiq (AS), this praised personality. 

Birth and Lineage

Ja'far b. Muhammad b. 'Ali b. al-Husayn b. 'Ali b. Abi Talib (AS), known as Imam Sadiq (AS), was born on April 20, 702, in Medina. His father was Imam Muhammad al-Baqir (AS), and his mother was Umm Farwa, the daughter of al-Qasim, son of Muhammad b. Abi Bakr [1]. He had the opportunity to spend twelve years of his life with his grandfather, Imam Sajjad (AS), and thirty-one years with his father. His title al-Sadiq, which literally means "truthful," was given to him, since he avoided any direct involvement in the uprisings of his time [2]. 

Imam Sadiq (AS) had ten children, among whom was Imam Musa al-Kazim (AS), who was born on 745 A.D. 

Imam Sadiq (AS) 's Life at the time of Umayyad's Caliphate 

After the martyrdom of Imam Baqir (AS), Imam Sadiq (AS) was chosen as the leader of Shia Muslims, which lasted thirty-four years. The period of Imam Sadiq (AS) 's leadership coincided with the reign of the last five Umayyad caliphs, including Hisham b. 'Abd al-Malik, Valid b. Yazid b. 'Abd al-Malik, Yazid b. Valid b. 'Abd al-Malik, Ibrahim b. Valid b. 'Abd al-Malik and Marwan b. Muhammad.

 While Imam Sadiq (AS) witnessed a period of hardship and restrain under the reign of Hisham, after some years due to the weakening of Umayyads, which finally led to the fall of this dynasty, he found the chance to engage in scholarly activities and promote the actual Islamic teachings. He held many secret gatherings and meetings in which up to four thousand people attended, Imam Sadiq (AS) transferred his knowledge to his students, which later quoted many Hadiths from him and turned into authentic sources for future Muslim scholars [3]. 

Imam Sadiq (AS) 's Leadership at the time of Abbasid's Caliphate

After the fall of the Umayyad dynasty, Imam Sadiq (AS) witnessed the rise of Abbasid caliphs and lived during the reign of two of them, including al-Saffah and al-Mansur al-Dawaniqi. During the time of the first Abbasid caliph, al-Saffah, which was a period of instability and social and political upheavals, being engaged mostly in abolishing the remaining of Umayyad dynasty and their followers, provided Imam Sadiq (AS) with an excellent chance to go on with his scholarly and religious efforts and attract as many students as he could. 

Nevertheless, with the coming of al-Mansur to the throne, a period of total suppression and severe restraint began. During his realm, people lived in utter terror, and any kind of opposition was punished severely. Therefore, al-Mansur considered Imam Sadiq (AS) and his followers as a threat to his throne, and since Imam Sadiq (AS) was a public figure respected by all the people, he couldn't hurt him directly. So, he tried to weaken Imam's (AS) reputation and social status by enticing his students to engage in a debate with Imam Sadiq (AS) and defeat him. But all their efforts were futile [4]. 

Al-Mansur made many attempts to bring harm to Imam Sadiq (AS) and summoned him a few times to his court, intending to assassinate him, yet he wasn't successful. Imam Sadiq (AS) generally didn't tend to meet al-Mansur and attend his court. Al-Mansur was offended by Imam Sadiq's (AS) manner and one day asked him, "Why don't you come to meet me in my court like others?" and Imam (AS) answered, "I didn't do anything to be afraid of you, and you don't benefit us in the hereafter so that I would have hope in you. This position of you is not a blessing to be congratulated by me, and you don't find it a disaster to be comforted by me. So why would I attend you?" [5]   

Fighting against Deviatory Movements 

During Imam Sadiq's (AS) life, some religious groups formed, which deviated from the true teachings of Islam and Prophet Muhammad's (PBUH&HP) tradition. To oppose these movements and save Islam from such deviations, Imam Sadiq (AS) held many debates with the heads of these groups and tried to bring their falsehood into the light. Or he would send his students to have discussions with them. He always advised his students and followers to be wary of such deviatory movements and cut all ties with them. 

Scholarly and Scientific Movement 

As it was mentioned above, Imam Sadiq (AS) enjoyed an excellent opportunity to spread his knowledge among as many people as he could, which resulted in the transmission of a significant number of hadiths from him to the future generation. Therefore, most of the hadiths in fiqh or theology are from Imam Sadiq (AS) [2]. Due to his significant role in spreading the true Islamic teachings, Twelver Shiism is often called Ja'fari School [3]. Moreover, he held many dialogues and debates with theologians and scholars of different sects and religions, and even atheists, in which he managed to prove the authenticity of his stance. Some of the most famous students of Imam al-Sadiq (a) are Zurara b. A'yan, Burayd b. Mu'awiya, Jamil b. Darraj, 'Abd Allah b. Muskan, 'Abd Allah b. Bukayr, Hammad b. 'Uthman, Hammad b. 'Isa, Aban b. 'Uthman, 'Abd Allah b. Sinan, Abu Basir, Hisham b. Salim, Hisham b. al-Hakam. 

Prominent Moral Characteristics

Imam Sadiq was famous for his piety, knowledge, abundant and devoted worship, and great generosity [7]. It is reported that he spent a significant part of his time praying, fasting, or saying dhikr (remembrance) [8].  

Many narrations are reported about his generosity and kind manner toward people who lived in poverty. For instance, "it is reported that the Imam (AS) gave four hundred dirhams to a beggar, and when he thanked the Imam (a), he (a) gave him his ring, which was worth 10,000 dirhams. According to another report, the Imam would put some bread, meat, and money in a bag and would take it to the houses of the poor and divide it among them, without letting them know who he was. Abu Ja'far al-Khath'ami reports that Imam al-Sadiq (a) gave him a bag of money and asked him to give it to someone from Banu Hashim without telling him from where the money was coming. When Abu Ja'far gave the money to that man, he prayed for the sender and told him that this person always sends him money, but Imam al-Sadiq (a) never sends him anything even though he is rich!" [9] 

Martyrdom

Imam Sadiq (AS) was martyred on 765 A.D. at the age of sixty-three, poisoned by order of al-Mansur al-Dawaniqi. He was buried in the al-Baqi' Cemetery beside his father, Imam Baqir (AS), his grandfather Imam Sajjad (AS), and his uncle Imam Hasan (AS) [10].

Eid al-Ghadir is one of the most important historical events celebrated by many Muslims on the 18th day of the last Islamic month, Dhu al-Hijjah. Ghadir Khum is the name of a pond near Mecca. It was a place for pilgrims, who had attended the ritual of Hajj, to greet and rest a short while before taking different routes to their homes.

The Message of Allah

After completing his last pilgrimage, which was the first Muslim’s great gathering -with more than 70 thousand people- in the presence of their leader, the Messenger of Allah, Prophet Muhammad (PBUH&HP) arrived at Ghadir Khum on the 18th of Dhu al-Hijjah where he received another revelation from God saying:

“O, Apostle! Deliver what has been sent down to you from your Lord, and if you do not, you will not have delivered His message, and Allah shall protect you from the people. Indeed Allah does not guide the faithless lot” (5:67)

Allah in this verse commanded the Prophet (PBUH&HP) to clarify what had been previously revealed regarding Ali (AS) [i] and told him not to worry about the reaction of the people in delivering His message, for He would protect His Messenger from them.

Prophet’s Concern for the Future of Muslims

Upon receiving the above verse, the caravan stopped in the valley of Ghadir at Prophet’s command. According to some sources, about 12,000 people from Yemen had come to attend that year’s Hajj, which was known as “The farewell pilgrimage” (Hajj-at-Alvida). Despite the different route that they had to take to their homes, they were asked by prophet Muhammad (PBUH&HP) to choose the way which passed the place of Ghadir, so that they could be present at the time when the incident of Ghadir was taking place.

Then he sent for all people who had gone ahead to return and waited for those who had fallen behind to arrive and gather. At noon that day, the Prophet (PBUH&HP) performed the prayer in congregation with a great population of people behind him. When the prayer was finished, Prophet Muhammad (PBUH&HP) ascended the pulpit his followers had set up from the camel saddles and gave his famous sermon in a loud voice. He started his speech by praising Allah, announced the heart-breaking news of his oncoming death and then stated:

 “Verily, I am leaving behind two precious things (thaqalayn) among you: The Book of God (Quran) and my kindred (itrah), my household (Ahl al Bayt), for indeed, the two will never separate until they come back to me by the Pond (of al Kawthar on the Judgement's Day)” [1].

The Prophet’s Authority over all Muslims

The Prophet (PBUH&HP), in an attempt to remind Muslims of his own authority over them, asked: “Who has more of a right over the believers than their own selves?” Everyone present proclaimed: “Allah and His Prophet know better.”

The Prophet (PBUH&HP) then said: “Allah is my master and I am the master of all the believers, and I have more right and authority over the believers than they have over their own selves.”

Imam Ali (AS), the Divinely Appointed Successor of the Prophet (PBUH&HP)

Thereupon, he took Imam Ali (AS)’s hand, raised it up and continued:

“Whomsoever I am his leader (Mawla), Ali (AS) is also his leader (Mawla). O’ Allah! Love those who love him (Ali (AS)) and oppose those who oppose him” [2].

The Angel of Revelation, Gabriel, once again descended by the order of Allah and revealed the following verse of the Quran:

“Today I have perfected your religion for you, and I have completed My blessing upon you, and I have approved Islam as your religion” (5:3).

Ghadir, The day of Congratulations and Happiness

This day has been marked in history as a Grand Eid for many Muslims since then. It is also known as the Day of Leadership (Imamate) and Mastership (Wilayat), which is among the critical beliefs of Islam and the axioms of this holy religion.

A large number of Muslims around the world hold special celebrations, congratulate one another on this day and say:

“All praise belongs to Allah who has made us amongst those who hold firm to the Mastership (Wilayat) of the Commander of the Faithful (Amir al-Muminin) -Ali ibn Abi Talib (AS)-  and the Imams” [3].

Notes:

[i] According to the narration of Yawm al-Dar (The Day of invitation to his Home), the Prophet(PBUH) was commissioned in the third year of his prophethood to declare his call to Islam openly. This is clearly stated in the Holy Quran:

وَأَنذِرْ عَشِيرَتَكَ الأَقْرَبِينَ.

“Warn the nearest of your kinsfolk” (26:214).

After this, the Prophet(PBUH), invited his close relatives to his uncle Abu Talib’s house, after having their meal, he started to say: O Children of Abd al-Muttalib. I swear to God I know of no one among the Arabs who could have brought anything better than I have brought for you. I have brought for you prosperity here and your future. God has ordered me to invite you to my religion. Who among you will assist me in being my brother, helper, and successor?

No one showed any interest except for Ali (AS) who was the youngest. He rose up, saying: “O Messenger of God. I will be your assistant in this affair.”

The Prophet (PBUH&HP) put his hand around Ali’s neck and said:

إنَّ هَذا أَخِي وَوَصِيِّي وَخَلِيفَتِي فِيكُمْ فَاسْمَعُوا لَهُ وَأَطِيعُوا.

“This brother of mine is my helper, and successor. Listen to him and obey his commands” [4].
