It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both), he stated that the fasting of mine was mentioned to the Prophet (peace and blessings of Allah be upon him), so the Prophet (peace and blessings of Allah be upon him) came to me and I offered him a cushion. That cushion was made of leather and filled with palm leaves. So the Prophet (peace and blessings of Allah be upon him) sat on the ground and the cushion was placed between me and the Prophet (peace and blessings of Allah be upon him). The Prophet (peace and blessings of Allah be upon him) said to me: "Are three fasts every month not sufficient for you?" I said: O Messenger of Allah! (That is too few), the Prophet (peace and blessings of Allah be upon him) said: "Five fasts." I said: O Messenger of Allah! (That is too few), the Prophet (peace and blessings of Allah be upon him) said: "Then keep seven." I said: O Messenger of Allah! (That is too few), the Prophet (peace and blessings of Allah be upon him) said: "Then keep nine." I said: O Messenger of Allah! (Nine are also few), the Prophet (peace and blessings of Allah be upon him) said: "Eleven." I said: O Messenger of Allah! (Even eleven are few), the Prophet (peace and blessings of Allah be upon him) said: "There are no fasts superior to the fasts of Dawud (peace be upon him), and they are the fasts of half the year, that is, fasting one day and breaking the fast the next day."
