When the companions of Imam Husayn (a.s.) perceived their loss and realized that they themselves were incapable of defending the Imam and his relatives, they hastened to lay their lives in the presence of Imam Husayn (a.s.). Then Abdullah and Abdul Rahman, the sons of Urwa Ghifari, came to the Imam and said, “Peace be upon you O Aba Abdillah! The enemy has reached us and have hastened towards you from all sides, hence we desire to be killed before you and sacrifice our lives for you.” Imam replied,
“Welcome! Come closer to me.”
They came closer to the Imam and started fighting with the enemies in his side. One of them said, “Verily the Bani Ghifar and Khandaf, as also Bani Nizar knows, that I fight the adulterous group with my clear-cut and swift sword, O nation! defend the sons of noble fathers against the enemies with Eastern swords and sharp spears.”
(Tabari) The narrator says that two Jabirite men, named Sayf bin Haris and Malik bin Abd, who were cousins and foster brothers, came closer to Imam Husayn (a.s.) while they were weeping. Imam asked them,
“O sons of my brother! Why do you weep? By Allah! I desire that your eyes would be glowing.”
They replied, “May Allah make us your ransom! We do not weep on account of ourselves, rather we weep for you. We see that you have been surrounded, while we are incapable of defending you.” Imam replied,
“O sons of my brother! May Allah reward you fairly for this conscience and sympathy.”
(Manaqib) Then they advanced further saying, “Peace be upon you O son of the Prophet of Allah”, and Imam too replied their salutations. Then they attacked and were ultimately martyred. (May Allah’s Mercy and Blessings be upon them).
