Uqbah consulted the Prophet (saws) about his sister who took a vow to perform hajj barefooted and bareheaded. So he said: Command her to cover her head and to ride, and to fast three days.

The Messenger of Allah (saws) came upon him (during their stay) at al-Hudaybiyyah. He then narrated the rest of the tradition. This version adds: "He asked: Do you have a sacrificial animal? He replied: No. He then said: Fast three days or give three sa's of dates to six poor people, giving one sa' to every two persons."

My father got me married to a lady of a noble family, and often used to ask my wife about me, and she used to reply, "What a wonderful man he is! He never comes to my bed, nor has he approached me since he married me." When this state continued for a long period, my father told the story to the Prophet who said to my father, "Let me meet him." Then I met him and he asked me, "How do you fast?" I replied, "I fast daily," He asked, "How long does it take you to finish the recitation of the whole Qur'an?" I replied, "I finish it every night." On that he said, "Fast for three days every month and recite the Qur'an (and finish it) in one month." I said, "But I have power to do more than that." He said, "Then fast for three days per week." I said, "i have the power to do more than that." He said, "Therefore, fast the most superior type of fasting, (that is, the fasting of (prophet) David who used to fast every alternate day; and finish the recitation of the whole Qur'an In seven days." I wish I had accepted the permission of Allah's Apostle as I have become a weak old man. It is said that `Abdullah used to recite one-seventh of the Qur'an during the day-time to some of his family members, for he used to check his memorization of what he would recite at night during the daytime so that it would be easier for him to read at night. And whenever he wanted to gain some strength, he used to give up fasting for some days and count those days to fast for a similar period, for he disliked to leave those things which he used to do during the lifetime of the Prophet.

The family of Muhammad did not eat their fill for three successive days till he died.

The Prophet said, "The width between the two shoulders of a Kafir (disbeliever) will be equal to the distance covered by a fast rider in three days."

Allah's Apostle entered upon me and said, "Have I not been informed that you offer prayer all the night and fast the whole day?" I said, "Yes." He said, "Do not do so; Offer prayer at night and also sleep; Fast for a few days and give up fasting for a few days because your body has a right on you, and your eye has a right on you, and your guest has a right on you, and your wife has a right on you. I hope that you will have a long life, and it is sufficient for you to fast for three days a month as the reward of a good deed, is multiplied ten times, that means, as if you fasted the whole year." I insisted (on fasting more) so I was given a hard instruction. I said, "I can do more than that (fasting)" The Prophet said, "Fast three days every week." But as I insisted (on fasting more) so I was burdened. I said, "I can fast more than that." The Prophet said, "Fast as Allah's prophet David used to fast." I said, "How was the fasting of the prophet David?" The Prophet said, "One half of a year (i.e. he used to fast on alternate days). '

The Prophet said, "A woman should not travel for more than three days except with a Dhi-Mahram (i.e. a male with whom she cannot marry at all, e.g. her brother, father, grandfather, etc.) or her own husband.)"

My friend (the Prophet) advised me to do three things and I shall not leave them till I die, these are: To fast three days every month, to offer the Duha prayer, and to offer witr before sleeping.

My friend (the Prophet ) advised me to observe three things: (1) to fast three days a month; (2) to pray two rak`at of Duha prayer (forenoon prayer); and (3) to pray witr before sleeping.

The Prophet stayed with Safiya bint Huyai for three days on the way of Khaibar where he consummated his marriage with her. Safiya was amongst those who were ordered to use a veil.

Allah's Apostle said, "Do not hate one another, and do not be jealous of one another, and do not desert each other, and O, Allah's worshipers! Be brothers. Lo! It is not permissible for any Muslim to desert (not talk to) his brother (Muslim) for more than three days."

A man who wants to perform the Hajj (from Mecca) can perform the Tawaf around the Ka`ba as long as he is not in the state of Ihram till he assumes the Ihram for Hajj. Then, if he rides and proceeds to `Arafat, he should take a Hadi (i.e. animal for sacrifice), either a camel or a cow or a sheep, whatever he can afford; but if he cannot afford it, he should fast for three days during the Hajj before the day of `Arafat, but if the third day of his fasting happens to be the day of `Arafat (i.e. 9th of Dhul-Hijja) then it is no sin for him (to fast on it). Then he should proceed to `Arafat and stay there from the time of the `Asr prayer till darkness falls. Then the pilgrims should proceed from `Arafat, and when they have departed from it, they reach Jam' (i.e. Al-Muzdalifa) where they ask Allah to help them to be righteous and dutiful to Him, and there they remember Allah greatly or say Takbir (i.e. Allah is Greater) and Tahlil (i.e. None has the right to be worshipped but Allah) repeatedly before dawn breaks. Then, after offering the morning (Fajr) prayer you should pass on (to Mina) for the people used to do so and Allah said:-- "Then depart from the place whence all the people depart. And ask for Allah's Forgiveness. Truly! Allah is Oft-Forgiving, Most Merciful." (2.199) Then you should go on doing so till you throw pebbles over the Jamra.

My ears heard and my heart grasped (the statement which) the Prophet said, "The period for keeping one's guest is three days (and don't forget) his reward." It was asked, "What is his reward?" He said, "In the first night and the day he should be given a high class quality of meals; and whoever believes in Allah and the Last Day, should entertain his guest generously; and whoever believes in Allah and the Last Day should talk what is good (sense) or keep quiet."
