The Prophet (saws) said: The month consists of twenty-nine days, but do not fast till you sight it (the moon) and do not break your fast till you sight it. If the weather is cloudy, calculate it thirty days. When the twenty-ninth of Sha'ban came, Ibn Umar would send someone (who tried) to sight the moon for him. If it was sighted, then well and good; in case it was not sighted, and there was no cloud and dust before him (on the horizon), he would not keep fast the next day. If there appeared (on the horizon) before him cloud or dust, he would fast the following day. Ibn Umar would end his fasting alone with the people, and did not follow this calculation.

Whenever the Prophet returned from a journey and observed the walls of Medina, he would make his Mount go fast, and if he was on an animal (i.e. a horse), he would make it gallop because of his love for Medina.

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.

I heard the Prophet saying, "Indeed, anyone who fasts for one day for Allah's Pleasure, Allah will keep his face away from the (Hell) fire for (a distance covered by a journey of) seventy years."

Once Um Sulaim was (with the women who were) in charge of the luggage on a journey, and Anjashah, the slave of the Prophet, was driving their camels (very fast). The Prophet said, "O Anjash! Drive slowly (the camels) with the glass vessels (i.e., ladies).

The Prophet (saws) commanded to apply collyrium mixed with musk at the time of sleep. He said: A man who is fasting should abstain from it.

Abu Dawud said: Yahya b. Ma'in said to me: This tradition about the use of collyrium is munkar (i.e. contradicts the sound traditions on the subject).

The Messenger of Allah (saws) said: Gabriel (saws) led me in prayer at the House (i.e. the Ka'bah). He prayed the noon prayer with me when the sun had passed the meridian to the extent of the thong of a sandal; he prayed the afternoon prayer with me when the shadow of everything was as long as itself; he prayed the sunset prayer with me when one who is fasting breaks the fast; he prayed the night prayer with me when the twilight had ended; and he prayed the dawn prayer with me when food and drink become forbidden to one who is keeping the fast.

On the following day he prayed the noon prayer with me when his shadow was as long as himself; he prayed the afternoon prayer with me when his shadow was twice as long as himself; he prayed the sunset prayer at the time when one who is fasting breaks the fast; he prayed the night prayer with me when about the third of the night had passed; and he prayed the dawn prayer with me when there was a fair amount of light.

Then turning to me he said: Muhammad, this is the time observed by the prophets before you, and the time is anywhere between two times.

A man asked the Prophet (saws) whether one who was fasting could embrace (his wife) and he gave him permission; but when another man came to him, and asked him, he forbade him. The one to whom he gave permission was an old man and the one whom he forbade was a youth.

The Messenger of Allah (saws) had himself cupped when he was fasting.

Abu Dawud said: Wuhaib b. Khalid narrated a similar tradition from Ayyub through a different chain of narrators. Ja'far b. Rabi'ah and Hisham, that is, Ibn Hassan, narrated a similar tradition from 'Ikrimah on the authority of Ibn 'Abbas.

Yahya related to me from Malik that he had heard that the people of knowledge did not disapprove of people fasting using tooth-sticks at any hour of the day in Ramadan, whether at the beginning or the end, nor had he heard any of the people of knowledge disapproving of or forbidding the practice.

Yahya said that he heard Malik say, about fasting for six days after breaking the fast at the end of Ramadan, that he had never seen any of the people of knowledge and fiqh fasting them. He said, "I have not heard that any of our predecessors used to do that, and the people of knowledge disapprove of it and they are afraid that it might become a bida and that common and ignorant people might join to Ramadan what does not belong to it, if they were to think that the people of knowledge had given permission for that to be done and were seen doing it.

Yahya said that he heard Malik say, "I have never heard any of the people of knowledge and fiqh and those whom people take as an example forbidding fasting on the day of jumua. Fasting on it is good, and I have seen one of the people of knowledge fasting it, and it seemed to me that he was keen to do so."

That the Messenger of Allah (saws) said: "Whoever takes a false oath to deprive a Muslim of his wealth, he will meet Allah while He is angry with him."

Al-Ash'ath bin Qais said: "It is about me, by Allah! There was a dispute about some land between myself and a man from the Jews who denied my ownership of it, so I took him to the Prophet (saws). The Messenger of Allah (saws) said to me: 'Do you have any proof ?' I said: 'No'. So he said to Jew: 'Take an oath.' I said: 'O Messenger of Allah! If he takes an oath then my property will be gone!' So Allah, Most High revealed: Verily those who purchase a small gain at the cost of Allah's Covenant and their oaths.. until the end of the Ayah."

[Abu 'Eisa said:] There are narrations on this topic from Wa'il bin Hujr, Abu Musa, Abu Umamah bin Tha'labah Al-Ansari, and 'Imran bin Husain. The Hadith of Ibn Mas'ud is a Hasan Sahih Hadith.

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.

Once there was a feeling of fright at Medina, so Allah's Apostle rode a horse belonging to Abu Talha and (on his return) he said, "We have not seen anything (fearful), but we found this horse very fast."

There was a state of fear in Medina. Allah's Apostle rode a horse belonging to Abu Talha (in order to see the matter). The Prophet said, "We could not see anything, and we found that horse like a sea (fast in speed).

AbuBakr ibn AbdurRahman reported on the authority of a Companion of the Prophet (saws): I saw the Prophet (saws) commanding the people while he was travelling on the occasion of the conquest of Mecca not to observe fast. He said: Be strong for your enemy. The Messenger of Allah (saws) fasted himself.

Narrated AbuBakr:

A man who narrated his tradition to me said: I have seen the Messenger of Allah (saws) in al-Arj pouring water over his head while he was fasting, either because of thirst or because of heat.

Abu Dawud said: 'Alqamah was a Murji'i.

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to be cupped while he was fasting. Nafi said, "He later stopped doing that, and would not be cupped when he was fasting until he had broken the fast."

"The Messenger of Allah (saws) said: meaning: Allah Mighty and Sublime is He says: 'The Mujahid in My cause, he has guarantee fro Me. If I I seize him, I cause him to inherit Paradise, and if I return him, I return him with a reward or spoils of war.'"

[He said:] This Hadith is Gharib Sahih from this route.

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.

There was a feeling of fright in Medina, so the Prophet borrowed a horse called Mandub belonging 'to Abu Talha and mounted it. (On his return), he said, "I did not see anything of fright and I found this horse very fast."

On the days of the conquest of Mecca, when Mecca was captured, Fatimah came and sat on the left side of the Messenger of Allah (saws), and Umm Hani was on his right side. A slave-girl brought a vessel which contained some drink; she gave it to him and he drank of it. He then gave it to Umm Hani who drank of it. She said: Messenger of Allah, I have broken my fast; I was fasting. He said to her: Were you making atonement for something? She replied: No. He said: Then it does not harm you if it was voluntary (fast).

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."
