I was an interpreter between the people and Ibn `Abbas. Once Ibn `Abbas said that a delegation of the tribe of `Abdul Qais came to the Prophet who asked them, "Who are the people (i.e. you)? (Or) who are the delegates?" They replied, "We are from the tribe of Rabi`a." Then the Prophet said to them, "Welcome, O people (or said, "O delegation (of `Abdul Qais).") Neither will you have disgrace nor will you regret." They said, "We have come to you from a distant place and there is the tribe of the infidels of Mudar intervening between you and us and we cannot come to you except in the sacred month. So please order us to do something good (religious deeds) and that we may also inform our people whom we have left behind (at home) and that we may enter Paradise (by acting on them.)" The Prophet ordered them to do four things, and forbade them from four things. He ordered them to believe in Allah Alone, the Honorable the Majestic and said to them, "Do you know what is meant by believing in Allah Alone?" They replied, "Allah and His Apostle know better." Thereupon the Prophet said, "(That means to testify that none has the right to be worshipped but Allah and that Muhammad is His Apostle, to offer prayers perfectly, to pay Zakat, to observe fasts during the month of Ramadan, (and) to pay Al-Khumus (one fifth of the booty to be given in Allah's cause)." Then he forbade them four things, namely Ad-Dubba.' Hantam, Muzaffat (and) An-Naqir or Muqaiyar (These were the names of pots in which alcoholic drinks used to be prepared). The Prophet further said, "Memorize them (these instructions) and tell them to the people whom you have left behind."

Allah's Apostle was informed that I have said: "By Allah, I will fast all the days and pray all the nights as long as I live." On that, Allah's Apostle asked me. "Are you the one who says: 'I will fast all the days and pray all the nights as long as I live?' " I said, "Yes, I have said it." He said, "You cannot do that. So fast (sometimes) and do not fast (sometimes). Pray and sleep. Fast for three days a month, for the reward of a good deed is multiplied by ten time, and so the fasting of three days a month equals the fasting of a year." I said, "O Allah's Apostle! I can do (fast) more than this." He said, "Fast on every third day. I said: I can do (fast) more than that, He said: "Fast on alternate days and this was the fasting of David which is the most moderate sort of fasting." I said, "O Allah's Apostle! I can do (fast) more than that." He said, "There is nothing better than that."

Yahya related to me from Malik from Abu'n Nadr, the mawla of Umar ibn Ubaydullah, from Abu Salama ibn Abd ar-Rahman that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, "The Messenger of Allah, may Allah bless him and grant him peace, used to fast for so long that we thought he would never stop fasting, and he would go without fasting for so long that we thought he would never fast again. I never saw the Messenger of Allah, may Allah bless him and grant him peace, fast for a complete month except for Ramadan, and I never saw him do more fasting in any one month than he did in Shaban.'

While we were sitting with the Prophet a man came and said, "O Allah's Apostle! I have been ruined." Allah's Apostle asked what was the matter with him. He replied "I had sexual intercourse with my wife while I was fasting." Allah's Apostle asked him, "Can you afford to manumit a slave?" He replied in the negative. Allah's Apostle asked him, "Can you fast for two successive months?" He replied in the negative. The Prophet asked him, "Can you afford to feed sixty poor persons?" He replied in the negative. The Prophet kept silent and while we were in that state, a big basket full of dates was brought to the Prophet . He asked, "Where is the questioner?" He replied, "I (am here)." The Prophet said (to him), "Take this (basket of dates) and give it in charity." The man said, "Should I give it to a person poorer than I? By Allah; there is no family between its (i.e. Medina's) two mountains who are poorer than I." The Prophet smiled till his premolar teeth became visible and then said, 'Feed your family with it."

Allah's Apostle said to me, "O `Abdullah! Have I not been informed that you fast during the day and offer prayers all the night." `Abdullah replied, "Yes, O Allah's Apostle!" The Prophet said, "Don't do that; fast for few days and then give it up for few days, offer prayers and also sleep at night, as your body has a right on you, and your wife has a right on you, and your guest has a right on you. And it is sufficient for you to fast three days in a month, as the reward of a good deed is multiplied ten times, so it will be like fasting throughout the year." I insisted (on fasting) and so I was given a hard instruction. I said, "O Allah's Apostle! I have power." The Prophet said, "Fast like the fasting of the Prophet David and do not fast more than that." I said, "How was the fasting of the Prophet of Allah, David?" He said, "Half of the year," (i.e. he used to fast on every alternate day). Afterwards when `Abdullah became old, he used to say, "It would have been better for me if I had accepted the permission of the Prophet (which he gave me i.e. to fast only three days a month).
