It has been narrated on the authority of Abu Wa'il who said: Sahal bin Hunaif stood up on the Day of Siffin and said: O ye people, blame yourselves (for want of discretion); we were with the Messenger of Allah ( صلی اللہ علیہ وسلم ) on the Day of Hudaibiya. If we had thought it fit to fight, we could fight. This was in the truce between the Messenger of Allah ( صلی اللہ علیہ وسلم ) and the polytheists. Umar bin Khattab came, approached the Messenger of Allah ( صلی اللہ علیہ وسلم ) and said: Messenger of Allah, aren't we fighting for truth and they for falsehood? He replied: By all means. He asked: Are not those killed from our side in Paradise and those killed from their side in the Fire? He replied: Yes. He said: Then why should we put a blot upon our religion and return, while Allah has not decided the issue between them and ourselves? He said: Son of Khattab, I am the Messenger of Allah. Allah will never ruin me. (The narrator said): Umar went away, but he could not contain himself with rage. So he approached Abu Bakr (RA) and said: 'Abu Bakr, aren't we fighting for truth and they for falsehood? He replied: Yes. He asked: Aren't those killed from our side in Paradise and those killed from their side in the Fire? He replied: Why not? He (then) said: Why should we then disgrace our religion and return while God has not yet decided the issue between them and ourselves? Abu Bakr (RA) said: Son of Khattab, verily, he is the Messenger of Allah, and Allah will never ruin him. (The narrator continued): At this (a Sura of) the Qur'an (giving glad tidings of the victory) was revealed to the Messenger of Allah ( صلی اللہ علیہ وسلم ) . He sent for Umar and made him read it. He asked: Is (this truce) a victory? He (the Messenger of Allah) ( صلی اللہ علیہ وسلم ) replied: Yes. At this Umar was pleased, and returned.
