Hanzala asked Husayn ibn Ali's permission to recite the Quran 40:30-33 to the army of Kufa: "O my people! Indeed I fear for you [a day] like the day of the [heathen] factions; like the case of the people of Noah, of ʿAd and Thamud, and those who were after them, and Allah does not desire any wrong for [His] servants. O my people! I fear for you a day of mutual distress calls, a day when you will turn back [to flee], not having anyone to protect you from Allah, and whomever Allah leads astray has no guide."
He then said: "O people! do not kill Husayn; you will be destroyed with a divine punishment, and whoever tells lies will be disappointed."
Then Husayn said: "O Ibn Sa'd! May God bless you. They deserved the punishment when they rejected your call and attacked you to shed your blood and the blood of your friends, let alone now that they have martyred your pious friends."
Then Hanzala said: "May I be thy ransom! You are right. You are more knowledgeable than me with respect to religion and you understand it better. Let us go to the afterlife and join our brothers… God's blessings be upon you, O Aba 'Abd Allah, and your pure household. May God make me your companion in the Heaven."
While Husayn was saying "Amin", Hanzala went to the battlefield, and was martyred on the Day of Ashura 61/680 after killing some people from the army of Kufa.[5][6]
