Once the Prophet set out in the month of Ramadan. He observed fasting till he reached a place called Kadid where he broke his fast.

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, "Only some one who makes the intention to fast before dawn (actually) fasts."

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.

27 Yahya related to me from Malik that he had heard that Umar ibn al-Khattab, if he was travelling in Ramadan and knew that he would reach Madina at the begining of the day ,would do so fasting.

Yahya said that Malik said, "Someone who is travelling and knows that he will be reaching his people in the first part of the day, and then dawn breaks before he gets there, should be fasting when he gets there."

Malik said, "Someone who intends to go away (on a journey) in Ramadan, and then dawn breaks while he is still on his land before he has left, should fast that day."

Malik said that a man who returns from a journey in Ramadan and is not fasting may have sexual intercourse with his wife if he wishes, if she is not fasting and she has just become pure after her menses.

Allah's Apostle forbade Al-Wisal (fasting continuously for more than one day without taking any meals). A man from the Muslims said, "But you do Al-Wisal, O Allah's Apostle!" Allah's Apostle I said, "Who among you is similar to me? I sleep and my Lord makes me eat and drink." When the people refused to give up Al-Wisal, the Prophet fasted along with them for one day, and did not break his fast but continued his fast for another day, and when they saw the crescent, the Prophet said, "If the crescent had not appeared, I would have made you continue your fast (for a third day)," as if he wanted to punish them for they had refused to give up Al-Wisal.

Abu Bakr said, "By Allah! If they (pay me the Zakat and) withhold even a young (female) goat which they used to pay during the lifetime of Allah's Apostle, I will fight with them for it." `Umar said, "It was nothing but Allah Who opened Abu Bakr's chest towards the decision to fight, and I came to know that his decision was right."

I said, "O Allah's Apostle! We have slaughtered a young sheep of ours and have ground one Sa of barley. So, I invite you along with some persons." So, the Prophet said in a loud voice, "O the people of the Trench! Jabir had prepared "Sur" so come along."

[Al-Bukhari and Muslim].

The narration in Al-Bukhari adds: The Messenger of Allah (PBUH) said, "The young should greet the elderly.''

The Prophet (saws) said: Go in Allah's name, trusting in Allah, and adhering to the religion of Allah's Apostle. Do not kill a decrepit old man, or a young infant, or a child, or a woman; do not be dishonest about booty, but collect your spoils, do right and act well, for Allah loves those who do well.

The Prophet said (to his companions), "Do not fast Al-Wisal." They said, "But you fast Al-Wisail." He said, "I am not like you, for at night my Lord feeds me and makes me drink." But the people did not give up Al-Wisal, so the Prophet fasted Al-Wisal with them for two days or two nights, and then they saw the crescent whereupon the Prophet said, "If the crescent had delayed, I would have continued fasting (because of you)," as if he wanted to vanquish them completely (because they had refused to give up Al Wisal).

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)."

I was with the Prophet on a journey, and he observed the fast till evening. The Prophet said to a man, "Get down and mix Sawiq with water for me." He replied, "Will you wait till it is evening?" The Prophet said, "Get down and mix Sawiq with water for me; when you see night falling from this side, the fasting person should break his fast."

A woman made a voyage and vowed that she would fast one month if Allah made her reach her destination with peace and security. Allah made her reach her destination with security but she died before she could fast. Her daughter or sister (the narrator doubted) came to the Messenger of Allah (saws). So he commanded to fast on her behalf.

Asma bint Abi Bakr said, "We broke our fast during the lifetime of the Prophet on a cloudy day and then the sun appeared." Hisham was asked, "Were they ordered to fast in lieu of that day?" He replied, "It had to be made up for." Ma`mar said, "I heard Hisham saying, "I don't know whether they fasted in lieu of that day or not."

Allah's Apostle said, "When night falls from this side and the day vanishes from this side and the sun sets, then the fasting person should break his fast."

Yahya related to me from Malik from Yazid ibn Abdullah ibn al- Hadi from Abu Murra, the mawla of Umm Hani, the sister of Aqil ibn Abi Talib, that Abdullah ibn Amr ibn al-As told him that he had visited his father Amr ibn al-As and found him eating. His father had invited him to eat, and when he replied that he was fasting, his father said, "These are the days on which the Messenger of Allah, may Allah bless him and grant him peace, forbade us to fast, and told us to break the fast on them."

Malik said, "These days are the days of tashriq."

The father or Uncle of Mujibah al-Bahiliyyah visited the Messenger of Allah (saws). He then went away and came to him (again) after one year when his condition and appearance had changed.

He said: Messenger of Allah, do you not recognize me? He asked: Who are you? He replied: I am al-Bahili who came to you last year. He said: What has changed you? You were looking well, then you were good in appearance? He said: I have only food at night since I departed from you.

Thereupon the Messenger of Allah (saws) said: Why did you torment yourself? Fast during Ramadan (the month of patience) and fast for one day every month. He said: Increase it for me, for I have (more) strength. He said: Fast two days. He again said: Increase it for me. He said: Fast three days. He again said: Increase it for me. He said: Fast during the inviolable months and then stop; fast during the inviolable months and then stop; fast during the inviolable months and then stop. He indicated by his three fingers, and joined them and then opened them.

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to send the zakat al-fitr to the one with whom it was collected together two or three days before the day of breaking the fast.

The Messenger of Allah (saws) used to command us to fast the days of the white (nights): thirteenth, fourteenth and fifteenth of the month. He said: This is like keeping perpetual fast.

Ibn 'Umar (Allah be pleased with them) reported that the people of pre-Islamic days used to sell the meat of the slaughtered camel up to habal al-habala. And habal al-habala implies that a she-camel should give birth and then the (born one should grow young) and become pregnant. Allah's Messenger (may peace be upon him) forbade them that (this transaction).

Abu Dawud said : the words “male and female” narrated, by Ayyub and ‘Abd Allah al Umar were narrated in their version on the authority of Nafi’.

This hadith is narrated on the authority of Hisham with the same chain of transmitters, but he made no mention in the first part of the hadith that the Messenger of Allah (may peace be upon him) used to observe fast, and said about the second part that he abandoned the (fast) of Ashura, and he who wished observed the fast and who wished otherwise abandoned it, and he did not hold it as the words of the Apostle of Allah (may peace be upon him) as mentioned in the narration transmitted by Jarir.

The Prophet or Abul-Qasim said, "Start fasting on seeing the crescent (of Ramadan), and give up fasting on seeing the crescent (of Shawwal), and if the sky is overcast (and you cannot see it), complete thirty days of Sha'ban."
