Love and kindness are two of the main components of Islam. To the extent that Allah regards Prophet Muhammad (PBUH&HP) as kind and benevolent towards people of all nations in the Holy Quran: “We did not send you but as a mercy to all the nations (21:107).” And says that if he had not been gentle to people, they would have surely scattered from around him. (3:159)

Imam Hussain (AS), following in his grandfather’s footsteps, also placed particular emphasis on this prophetic trait and ethic. He was not only gentle and affectionate towards his children, family, and relatives, but also showed great care, compassion, and respect towards others, even his enemies. The whole Fifty-seven years of Imam Hussain (AS)’s life are replete with such exemplary behavior. He did not give up this attitude towards others even in the hardest situations, like when he was at war with his enemies in the desert of Karbala.

Here we will see only a few examples of Imam Hussain’s (AS) love and affection towards others in the last days of his life: 

Imam Hussain (AS)'s Attention to Children:

During the battle, in Karbala, Imam Hussain (AS) would sympathize with his family and children and treated them with love and care whenever possible. 

Imam Hussain (AS)'s Attention and Respect towards His Companions:

At the night before Ashura, Imam Hussain (AS) refers to his relatives and companions as the best ones ever: “It is a fact that I am not aware of any companions more faithful and honest than my companions and any relatives more righteous and kind than my relatives.” Imam Hussain (AS) then permits all his companions to leave him without any restrictions to save their lives, but they don’t accept. On several occasions, such as the morning of Ashura, he addresses them with the most respectful titles like “the nobles.” Also, it is narrated that during the battle, Imam (AS) would be present near his martyred companions himself, and wept and prayed for them one by one, even for the African slave, Jawn.

Imam Hussain (AS)'s Compassion for His Enemy:

Imam Hussain (AS) never used foul language or even one wrong word against his enemy. He would not hesitate to take advantage of any opportunity to stop the violence and invite his enemies to peace. For instance, when Imam Hussain (AS) and his companions came across Hur, and his army, who were supposed to intercept Imam Hussain (AS) outside Kufa, Imam Hussain (AS) quenched their thirst. He, along with his companions, also even gave water to their horses.

Another example of Imam Hussain’s compassion for the enemy is his encounter with Umar ibn Sa’ad and the other commanders of the enemy’s army on the day of Ashura, and his effort to persuade them to stop the war. In fact, Imam (AS) did not want them to commit an unforgivable sin- i.e., killing the innocent Imam (AS) and his companions- that would make them end up in hell.

So, it was only Imam Hussain's (AS) love and mercy towards humankind that touched every one’s heart, even his enemy to the extent that some of whom, like Hur, would surrender to righteousness, accompany Imam Hussain (AS), perform their prayer in congregation behind him, fight against his enemy and finally be martyred along with him. 

This is Imam Hussain’s (AS) lesson of tolerance and benevolence towards all human beings, which is beyond any religion or sect; that if one does not want to follow a particular religion, he/she can at least live a human life [3].
