The Holy Quran is replete with examples of men who stood for the truth and those who opposed it. The former sacrificed everything they had to defend the truth and the latter was ready to destroy everything around them to satiate their greed and selfishness.

The Book of Allah invites us to reflect upon personalities, nations, and events of the past. Whether it is pure men like Prophet Ibrahim (AS), Prophet Musa (AS) and Prophet Isa (AS) or evil men who opposed them and their mission like Nimrood, Firon (Pharoah), or Bani Israil, all of them have a lesson for us. These are not just stories to read and move on, they contain messages for our lives. And rightly so, we read in the Holy Quran:
"There is certainly a moral in their accounts for those who possess intellect. This [Quran] is not a fabricated discourse; rather, it is a confirmation of what was [revealed] before it, and an elaboration of all things, and a guidance and mercy for a people who have faith. (12:111)

Similarly, Imam Ali (AS) says: Learn lessons from past events for future events, because they are similar to one another. (Nahjul Balagha Letter 69)
One such incident of the past that changed the history of Islam forever, is the event of Karbala. No mention of Karbala is complete without Hurr ibn Yazid Ar-Riyahi. He is an example for those who reflect upon his journey, his actions and his martyrdom. He encourages, inspires and motivates the believers through his actions in Karbala. 

Background

Hurr literally means a freeman in Arabic, and truly so he lived up to his name. 
Hurr Ibn Yazid Ar-Riyahi was the general of the Ummayad army dispatched from Kufa, (Iraq) to intercept Imam Al-Hussain (AS), the third infallible Imam. Ubaydullah ibn Ziyad, the newly appointed governor of Kufa issued the command to guard all entrances and exits to Kufa in order to intercept al-Hussain for an oath of allegiance to Yazid. Hurr was ordered along with his 1,000 soldiers to intercept Imam Hussain(AS) and his followers before they reached Kufa.

When he intercepted Imam Hussain (AS) at Dhu Hussam, Hurr and his men had ran out of water. The Imam(AS) ordered his companions to satiate Hurr and his army, including the cavalry. Hurr and his men offered their prayers with the Imam and listened to his sermons. However, on subsequent orders from the tyrant governor of Kufa, Ubaidullah Ibn Ziyad, Imam Hussain and his family were forced to encamp in Karbala. Hurr was of the notion that the Imam (AS) will not be killed in Karbala, he would somehow persuade him to go elsewhere. But he was perturbed when he realized that Umar Ibn Sa'ad who was sent by Ubaidullah had come with orders to kill Imam Hussain. On one hand was his position, family and wealth and on the other hand was the grandson of the Holy Prophet(PBUH&HP) and the son of Imam Ali (AS) and Lady Fatima (SA), supporting whom meant a certain death. These were the two options left for Hurr, just as the Holy Quran says:
 "Indeed We have guided him to the way, be he grateful or ungrateful." (76:3). 

What do we learn from Hurr?

Despite all odds, Hurr left the Army of Yazid, joined Imam Hussain (AS) and won the honor of being the first martyr of Karbala. All the glitter of the world, his power, rank, wealth and children did not stop him from joining his master Hussain(AS). 
Ashura and Karbala were not be bound by time or geographical location. Almost 14 centuries have passes by but human beings from different parts of the world, belonging to different races and religions continue to mourn for Imam Hussain(AS) and take inspiration from him and his mission.
Just as Karbala continues to inspire us, the magnanimous personality of Hurr continues to inspire and guide us. Hurr chose good over bad, truth over falsehood, hereafter over the transient world. If we claim to be followers and lovers of Imam Hussain(AS) we need to turn towards the Hussain of our time and follow the teachings of Imam Hussain(AS). Imam Hussain(AS) gave everything he had to protect and preserve the teachings of Islam and by helping Hussain(AS) in his cause, Hurr achieved this lofty position of being Imam Hussain's(AS) helper. Thus, if Hurr truly motivates us, we need to mend our ways and make ourselves capable of helping Imam Mahdi (AJ) the true inheritor of Imam Hussain's (AS) legacy.

The Hurr of Karbala teaches us that true love is incomplete without sacrifice. 

But, is the Hurr inside us ready to listen?

The death of a loved one, the problems at home or work, and even maintaining the Islamic regulations and orders might sometimes be challenging for us. In all these cases and many others, the patience to which Islam has invited can be enlightening for a Muslim. This patience is not merely passive waiting. Instead, patience in Islam directs us toward bearing things in a more steadfast and hopeful way.  

What is Patience in Islam?

The word patience in Islam has several meanings like limiting and constraining the self (Nafs), and, strengthening it against anxiety and discomfort [1]. Patience in Islam can be defined in two ways:

1. Patience Concerning the Islamic rules and Duties and in Worshiping Allah:

Being steadfast in doing what Islam and Allah have advised us to do and in preventing ourselves from whatever they have forbidden us to commit [2] & [4]. The duties that God has assigned to human beings, and especially those He has determined for Muslims, are not free of hardship. Hence, one might ignore some of them or abandon entirely or choose to be patient and experience their eternal joy: “so worship Him and have the patience for His worship” (19:65).

Moreover, being steadfast in avoiding sins and against committing evil deeds is the highest level of patience and the hardest one. Resisting the temptations and desires that appeal to evil deeds, to worldly positions or personal benefits against the collective interests, etc. is not easy, such that Prophet Joseph (AS) said: “And I do not acquit myself. Indeed, the soul is a persistent enjoiner of evil, except those upon which my Lord has mercy.” (12:53).   

2. Patience in our lives:  

Keeping the inner peace and serenity in difficulties and disasters such as  the loss of a loved one or some money, sickness or natural disasters, and having perseverance and persistence in those circumstances such that one keeps calm, does not complain, nor shows overreaction are the signs of patience in our personal lives: “And We will surely test you with something of fear and hunger and a loss of wealth and lives and fruits, but give good tidings to those who are patient.” (2:155) [3], [6]

The Manifestations of Patience in Islam

According to Prophet Muhammad (PBUH&HP) patience is manifested in the behavior of the one who believes in the other world, its rewards and punishments, is pious and considers this world as a temporary dwelling, and is aware of his/her mortality and the fact that one day he/she will be no more and the difficult moments will soon pass and be forgotten [5].

Four Characteristics of a Patient Person

Prophet Muhammad (PBUH&HP) has explained the characteristics of a patient person as follows [7]:

1. Is not lazy or indolent:  being lazy and not doing anything equals ignoring the rights of others, including family, friends, neighbors, etc., as well as those of oneself [7];

2. Does not get upset and disappointed:  believing that there is a wisdom behind every happening, a patient person does not lose his\her hope [7]. These are the ones that in case of sorrow, tell themselves that: “Indeed we belong to Allah, and indeed to Him, we will return.” (2:156);

3. Does not complain: a patient person does not complain [7] despite any difficulties that he\she faces, because he\she is satisfied with everything that God has considered for him\her to be the best thing that could happen. On the contrary, he\she asks God for the help and solution on that matter.

3. Controls his words: a patient person does not lose his temper when being frustrated or hurt and avoids insulting, slandering, and offensive words. 

When Is Patience Required?

According to a Hadith, patience is required on five occasions: 

•    A respected person who is humiliated: 

•    An honest person who is accused of something unfairly;  

•    One who invites to justice but is ignored; 

•    An innocent person who is hurt; 

•    The one who seeks justice is opposed [8]. 

If one faces these troubles with serenity instead of showing a sudden naïve reaction, and if he\she be patient and trust the divine support, sooner or later he/she will find justice.
