When Abu Samamah ‘Amr bin Abdullah Saedi saw his companions being killed one after the other, he turned towards Imam Husayn (a.s.) and said, “O Aba Abdillah! May I be your ransom! I see that this army has advanced closer to you. But Allah willing, they shall not be able to kill you until they have killed us. And I desire that I go to the presence of Almighty Allah having recited the Prayers (in your lead), whose time has already approached.” Then Imam lifted up his head and said,
“You have reminded the (time of) Prayers, may Allah join you with the worshippers and the reciters, and verily this is the prime time for Prayers.”
Then he said,
“Tell them to lift their hands off us until we have finished reciting the Prayers.”
Hearing this Haseen bin Tameem said, “Your Prayers are not accepted.” Habib bin Mazahir replied, “You think that the Prayers of the Progeny of the Prophet of Allah is not accepted, while the Prayers of you, a wine-bibber, is accepted”?
