Sahl bin Hunayf stood up on the day of Siffin and said, "People, accuse yourselves. We were with the Messenger of Allah ﷺ on the day of Hudaybiyah, and had we seen any cause for fighting, we would have fought. This was during the truce concluded between the Messenger of Allah ﷺ and the polytheists.Umar bin Khattab came and approached the Messenger of Allah ﷺ and asked, "Messenger of Allah, are we not in the right and they in the wrong?"He replied, "Yes."Umar asked, "Are not our slain in Paradise and theirs in the Fire?"He replied, "Yes."Umar said, "Then why should we accept humiliation in our religion and turn back when Allah has not yet judged between us and them?"The Prophet said, "Son of Khattab, I am the Messenger of Allah, and Allah will never forsake me."Umar left, unable to restrain his anger, and went to Abu Bakr. He said, "Abu Bakr, are we not in the right and they in the wrong?"Abu Bakr replied, "Yes."Umar asked, "Are not our slain in Paradise and theirs in the Fire?"Abu Bakr replied, "Yes."Umar said, "Then why should we accept humiliation in our religion and turn back when Allah has not yet judged between us and them?"Abu Bakr said, "Son of Khattab, he is the Messenger of Allah, and Allah will never forsake him."Then the Quran was revealed to the Messenger of Allah ﷺ announcing the victory, and he sent for Umar and recited it to him. Umar asked, "Messenger of Allah, is this truly a victory?"He replied, "Yes."Umar's heart was set at ease, and he returned satisfied.
