Sayyiduna Anas (may Allah be pleased with him) says that when this verse was revealed to the Prophet (peace and blessings be upon him): [Surah al-Fath: 1-2] "Indeed, We have granted you a clear victory, so that Allah may forgive you your former and later sins," when he (peace and blessings be upon him) was returning from al-Hudaybiyyah, there was grief and distress. He (peace and blessings be upon him) slaughtered the sacrificial animals and said: "This verse that has been revealed to me is dearer to me than the whole world." The Companions said: O Messenger of Allah (peace and blessings be upon him)! What will Allah do with us and with you? Then this verse was revealed: [Surah al-Fath: 5] "That Allah will admit the believing men and the believing women into gardens beneath which rivers flow," until he recited the complete verse.
