Abu al-Tayyah said: I heard Anas bin Malik (may Allah be pleased with him) say that on the day of the Conquest of Makkah the Ansar said: "By Allah! This is astonishing: our swords are soaked in the blood of Quraysh, and our spoils are being distributed among them." The Prophet (peace and blessings be upon him) came to know of this, so he (peace and blessings be upon him) called the Ansar specifically, and he (peace and blessings be upon him) said: "What is this that has reached us from you?" They said: "We were not ones to lie; what has reached you is correct." He (peace and blessings be upon him) said: "Are you not pleased that the people take away the spoils and you go to your homes with the Messenger of Allah (peace and blessings be upon him)? If the people were to walk in a valley, I would walk in the mountain pass of the Ansar."
Imam al-Shafi'i (may Allah have mercy on him) said: Concerning the one-fifth of the spoils, when it is separated out, those who speak say: We won these spoils; and by that they meant that the cause of its ownership was through them, and this was present in the speech of the Ansar. The Messenger of Allah (peace and blessings be upon him) said: "The one-fifth is mine, then it is returned among you." When the Messenger of Allah (peace and blessings be upon him) gave it to those who were distant, those of the Ansar who were close to him objected.
Imam al-Shafi'i (may Allah have mercy on him) said that it is narrated from Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) gave al-Aqra' and his companions from the fifth of the one-fifth.
