A man came to Allah's Apostle asking him about Islam, Allah's Apostle said, "You have to offer five compulsory prayers in a day and a night (24 hours)." The man asked, "Is there any more compulsory prayers for me?" Allah's Apostle said, "No, unless you like to offer Nawafil (i.e. optional prayers)." Allah's Apostle then added, "You have to observe fasts during the month of Ramadan." The man said, "Am I to fast any other days?' Allah's Apostle said, "No, unless you wish to observe the optional fast voluntarily." Then Allah's Apostle told him about the compulsory Zakat. The man asked, "Do I have to give anything besides?" Allah's Apostle said, "No, unless you wish to give in charity voluntarily." So, the man departed saying, "By Allah I will neither do more nor less than that." Allah's Apostle said, "If he has said the truth he will be successful."

When the delegate of `Abd Al-Qais came to Allah's Apostle, he said, "Who are the delegate?" They said, "The delegate are from the tribe of Rabi`a." The Prophet said, "Welcome, O the delegate, and welcome! O people! Neither you will have any disgrace nor will you regret." They said, "O Allah's Apostle! Between you and us there are the infidels of the tribe of Mudar, so please order us to do something good (religious deeds) that by acting on them we may enter Paradise, and that we may inform (our people) whom we have left behind, about it." They also asked (the Prophet) about drinks. He forbade them from four things and ordered them to do four things. He ordered them to believe in Allah, and asked them, "Do you know what is meant by belief in Allah?" They said, "Allah and His Apostle know best." He said, ''To testify that none has the right to be worshipped except Allah, the One, Who has no partners with Him, and that Muhammad is Allah's Apostle; and to offer prayers perfectly and to pay Zakat." (the narrator thinks that fasting in Ramadan is included), "and to give one-fifth of the war booty (to the state)." Then he forbade four (drinking utensils): Ad-Duba', Al56 Hantam, Al-Mazaffat and An-Naqir, or probably, Al-Muqaiyar. And then the Prophet said, "Remember all these things by heart and preach it to those whom you have left behind."

The Prophet (saws) said: Do not fast (for Ramadan) before the coming of the month until you sight the moon or complete the number (of thirty days); then fast until you sight the moon or complete the number (of thirty days).

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.'

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, once mentioned Ramadan and said, "Do not begin the fast until you see the new moon, and do not break the fast (at the end of Ramadan) until you see it. If the new moon is obscured from you, then work out (when it should be)."

Yahya related to me from Malik from Hisham ibn Urwa that his father used to be cupped while he was fasting and he would not then break his fast. Hisham added, "I only ever saw him being cupped when he was fasting."

Malik said, "Cupping is only disapproved of for some one who is fasting out of fear that he will become weak and if it were not for that, it would not be disapproved of. I do not think that a man who is cupped in Ramadan and does not break his fast, owes anything, and I do not say that he has to make up for the day on which he was cupped, because cupping is only disapproved of for someone fasting if his fast is endangered. I do not think that someone who is cupped, and is then well enough to keep the fast until evening, owes anything, nor does he have to make up for that day."

The Messenger of Allah (saws) used to count the days in Sha'ban in a manner he did not count any other month; then he fasted when he sighted the new moon of Ramadan; but if the weather was cloudy he counted thirty days and then fasted.

'A'isha reported that when the Messenger of Allah (may peace be upon him) decided upon doing any act, he continued to do it, and when he slept at night or fell sick he observed twelve rak'ahs during the daytime. I am not aware of Allah's Messenger (may peace be upon him) observing prayer during the whole of the night till morning, or observing fast for a whole month continuously except that of Ramadan.

Mansur al-Kalbi said: Dihyah ibn Khalifah once went out from a village of Damascus at as much distance as it measures between Aqabah and al-Fustat during Ramadan; and that is three miles. He then broke his fast and the people broke their fast along with him. But some of them disliked to break their fast. When he came back to his village, he said: I swear by Allah, today I witnessed a thing of which I could not even think to see. The people detested the way of the Messenger of Allah (saws) and his Companions. He said this to those who fasted. At this moment he said: O Allah, make me die.

I came to Abu Sa'id al-Khudri while he was giving his legal opinion to the people who bent down on him. So I waited to see hi when he was alone. When he became alone, I asked him about keeping fast while travelling. He said: we went out along with the Prophet (saws) in Ramadan in the year of conquest of Mecca. The Messenger of Allah (saws) fasted and we fasted until he reached a certain stage. He said: You have come near your enemy; the breaking of fast will bring you more strength. Then morning came when some of us fasted and other broke their fast. He (Abu Sa'id al-Khudri) said: We then proceeded and alighted at a stage. He said: You are going to attack your enemy tomorrow morning ; breaking the fast will bring you more strength ; so break your fast (i.e. do not keep fast). This resolution (of breaking the fast) took place (due to the announcement) from the Messenger of Allah (saws).

Abu Sa'id said: Then I found myself keeping fast along with the Prophet (saws) before and after that.

Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, "The day of Ashura was a day the Quraysh used to fast in the jahiliyya, and the Messenger of Allah, may Allah bless him and grant him peace, used also to fast it during the jahiliyya. Then when the Messenger of Allah, may Allah bless him and grant him peace, came to Madina he fasted it and ordered that it be fasted. Then Ramadan was made obligatory, and that became the fard instead of Ashura, but whoever wanted to, fasted it, and whoever did not want to, did not fast it."
