When Hurr saw that the people have resolved to kill Imam Husayn (a.s.), and when he heard Imam calling out:
“Is there none who would hasten to assist us in the name of Allah? Is there none who would defend the Household of the Prophet”?
Then Hurr told Umar bin Sa’ad, “O Umar! Then will you really fight this man”? He replied, “Yes, by Allah! The battle, which if goes smoothly, will result in the rolling of heads and cutting off the hands.” Hurr said, “Then is his proposal unacceptable to you”? Umar replied, “If the situation would have been in my hands, I would certainly have yielded to his request, but your commander will not accept it.”
Hurr then left him and stood alone far away from others, while his fellow traveler, named Qurrah bin Qays, was along with him. Hurr said, “O Qurrah! Have you fed your horse today”? He replied in the negative. Hurr said, “Then do you not desire quenching it’s thirst”? Qurrah says that I doubted that perhaps he wanted to skip away from the battle and did not like that I should see him going away, hence I said, “I shall now be doing so.” Hearing this Hurr moved away from there. Qurrah says that, “By Allah! If only Hurr had revealed to me what he intended, I too would have accompanied him to the presence of Imam Husayn (a.s.).” Then slowly Hurr started moving closer to Imam Husayn (a.s.).
Muhajir bin Aws told him, “O son of Yazid! What do you intend? Do you intend to lay siege”? Hurr did not answer him but was shivering. Muhajir said, “Verily your state seems dubious. I have never ever seen you in any battle in a similar state in which you are now. If I would have been questioned as to who is the most valorous among the Kufans, I would not hesitate to take your name. What is this state I presently see you in”? Hurr replied, “I find myself between Paradise and hell. And by Allah! I shall not exalt anything else over Paradise, even if I be cut into pieces or burnt.” Then Hurr struck his horse (Malhoof) and turned to go towards Imam Husayn (a.s.)
Hurr had kept his hands on his head (like a prisoner) and was saying, “O Allah! I am returning towards You, thus You accept me, for I have put fear into the hearts of Your friends and the children of the Prophet’s grandson.”
