Allah's Apostle said: Islam is based on (the following) five (principles):

1. To testify that none has the right to be worshipped but Allah and Muhammad is Allah's Apostle.

2. To offer the (compulsory congregational) prayers dutifully and perfectly.

3. To pay Zakat (i.e. obligatory charity) .

4. To perform Hajj. (i.e. Pilgrimage to Mecca)

5. To observe fast during the month of Ramadan.

Allah's Apostle said, "When the month of Ramadan starts, the gates of the heaven are opened and the gates of Hell are closed and the devils are chained."

Ibn Umar reported that the Messenger of Allah (may peace be upon him) prescribed Zakat-ul-Fitr of Ramadan one sa' of dates or one sa' of barley for every individual among the Muslims (whether) free man or slave, male or female, young or old.

Allah's Apostle set out towards Hunain in the month of Ramadan and some of the people were fasting while some others were not fasting, and when the Prophet mounted his she-camel, he asked for a tumbler of milk or water and put it on the palm of his hand or on his she-camel and then the people looked at him; and those who were not fasting told those who were fasting, to break their fast (i.e. as the Prophet had done so).

Allah's Apostle set out for Mecca in Ramadan and he fasted, and when he reached Al-Kadid, he broke his fast and the people (with him) broke their fast too. (Abu `Abdullah said, "Al-Kadid is a land covered with water between Usfan and Qudaid.")

Quraish used to fast on the day of 'Ashura' in the Pre-Islamic period, and Allah's Apostle too, used to fast on that day. When he came to Medina, he fasted on that day and ordered others to fast, too. Later when the fasting of the month of Ramadan was prescribed, he gave up fasting on the day of 'Ashura' and it became optional for one to fast on it or not.

The Messenger of Allah (saws) said to us: Seek it (laylat al-Qadr) on the seventeenth night of Ramadan, and on the twenty first night, and on the twenty-third night. He then kept silence.

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.

Yahya related to me from Malik from Ibn Shihab from Ubaydullah ibn Abdullah ibn Utba ibn Masud from Abdullah ibn Abbas that the Messenger of Allah, may Allah bless him and grant him peace, left for Makka in Ramadan during the year of the conquest, and fasted until he reached al-Kadid. He then broke the fast, and so everyone else did so as well. What people used to do was act according to whatever the Messenger of Allah, may Allah bless him and grant him peace, had done most recently.

The Prophet said, "The two months of `Id i.e. Ramadan and Dhul-Hijja, do not decrease (in superiority).

Jabir b Samura reported that the Messenger of Allah (may peace be upon him) commanded us to observe fast on the day of Ashura and exhorted us to do it and was particular about it But when (fasting) in Ramadan was made obligatory, he hence. forth neither commanded us nor forbade us, nor was he so particular about it.

The Messenger of Allah (saws) came to a man at al-Baqi' while he was cupping on the 18th of Ramadan ; he (the Prophet) was holding my hand. Thereupon he said: A man who cups and a man who gets himself cupped break their fast.

Abu Dawud said: The narrator Khalid al-Hadhdha' transmitted a similar tradition from Abu Qilabah through a different chain of narrators mentioned by the narrator Ayyub.

(The tribe of) Quraish used to fast on the day of Ashura' in the Pre-Islamic period, and then Allah's Apostle ordered (Muslims) to fast on it till the fasting in the month of Ramadan was prescribed; whereupon the Prophet said, "He who wants to fast (on 'Ashura') may fast, and he who does not want to fast may not fast."

Allah's Apostle used to fast till one would say that he would never stop fasting, and he would abandon fasting till one would say that he would never fast. I never saw Allah's Apostle fasting for a whole month except the month of Ramadan, and did not see him fasting in any month more than in the month of Sha'ban.

The Prophet said, "Whoever fasted the month of Ramadan out of sincere Faith (i.e. belief) and hoping for a reward from Allah, then all his past sins will be forgiven, and whoever stood for the prayers in the night of Qadr out of sincere Faith and hoping for a reward from Allah, then all his previous sins will be forgiven ."

Ibn Umar said that Allah's Messenger (way peace be upon him) prescribed the payment of Zakat-ul-Fitr (on breaking the fast) of Ramadan for people, for every freeman, or slave, male and female among the Muslims-one sa' of dried dates, or one sa' of barley.

This hadith has been narrated by 'A'isha (Allah be pleased with her) through another chain of transmitters.

Once I went to Abu- Sa`id Al-Khudri and asked him, "Won't you come with us to the date-palm trees to have a talk?" So Abu Sa`id went out and I asked him, "Tell me what you heard from the Prophet about the Night of Qadr." Abu Sa`id replied, "Once Allah's Apostle performed I`tikaf (seclusion) on the first ten days of the month of Ramadan and we did the same with him. Gabriel came to him and said, 'The night you are looking for is ahead of you.' So the Prophet performed the I`tikaf in the middle (second) ten days of the month of Ramadan and we too performed I`tikaf with him. Gabriel came to him and said, 'The night which you are looking for is ahead of you.' In the morning of the 20th of Ramadan the Prophet delivered a sermon saying, 'Whoever has performed I`tikaf with me should continue it. I have been shown the Night of "Qadr", but have forgotten its date, but it is in the odd nights of the last ten nights. I saw in my dream that I was prostrating in mud and water.' In those days the roof of the mosque was made of branches of date-palm trees. At that time the sky was clear and no cloud was visible, but suddenly a cloud came and it rained. The Prophet led us in the prayer and I saw the traces of mud on the forehead and on the nose of Allah's Apostle. So it was the confirmation of that dream."

Ibn `Abbas said, "Allah's Apostle travelled in the month of Ramadan and he fasted till he reached (a place called) 'Usfan, then he asked for a tumbler of water and drank it by the daytime so that the people might see him. He broke his fast till he reached Mecca." Ibn `Abbas used to say, "Allah's Apostle fasted and sometimes did not fast while traveling, so one may fast or may not (on journeys)"

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."

Qays ibn Talq said: Talq ibn Ali visited us on a certain day during Ramadan. He remained with us till evening and broke fast with us. He then stood up and led us in the witr prayer.

He then went to his mosque and led them in prayer. When the witr remained, he put forward another man and said: Lead your companions in the witr prayer, for I heard the Messenger of Allah (saws) as saying: There are no two witrs during one night.

The Prophet (saws) said: If anyone breaks his fast one day in Ramadan without a concession granted to him by Allah, a perpetual fast will not atone for it.

The Messenger of Allah (saws) said: If anyone has a riding beast which carries him to where he can get sufficient food, he should keep the fast of Ramadan wherever he is when it comes.

Yahya related to me from Malik from Zayd ibn Aslam from his brother Khalid ibn Aslam that Umar ibn al-Khattab once broke thefast on a cloudy day thinking that evening had come and the sun had set. Then a man came to him and said, "Amir al-muminin, the sun has come out,'' and Umar said, "That's an easy matter. It was our deduction (ijtihad)."

Malik said, "According to what we think, and Allah knows best, what he was referring to when he said, 'That's an easy matter' was making up the fast, and how slight the effort involved was and how easy it was. He was saying (in effect), 'We will fast another day in its place.' "

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.'

'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.

Ibn Abbas (Allah be pleased with him) reported that the Messenger of Allah (may peace be upon him) went out during the month of Ramadan in the year of Victory (when Mecca was conquered) and was fasting till he reached Kadid (a canal situated at a distance of forty-two miles from Mecca) and he then broke the fast. And it was the habit of the Companions of the Messenger of Allah (may peace be upon him) to follow him in every new thing (or act). So they followed him also (in this matter).
