The Prophet (ﷺ) never fasted a full month except the month of Ramadan, and he used to fast till one could say, "By Allah, he will never stop fasting," and he would abandon fasting till one would say, "By Allah, he will never fast."

I asked Anas about the fasting of the Prophet. He said "Whenever I liked to see the Prophet (ﷺ) fasting in any month, I could see that, and whenever I liked to see him not fasting, I could see that too, and if I liked to see him praying in any night, I could see that, and if I liked to see him sleeping, I could see that, too." Anas further said, "I never touched silk or velvet softer than the hand of Allah's Messenger (ﷺ) and never smelled musk or perfumed smoke more pleasant than the smell of Allah's Messenger (ﷺ)."

Two fasts and two kinds of sale are forbidden: fasting on the day of `Id ul Fitr and `Id-ul-Adha and the kinds of sale called Mulamasa and Munabadha.

(who fought in twelve Ghazawat in the company of the Prophet). I heard four things from the Prophet (ﷺ) and they won my admiration. He said; -1. "No lady should travel on a journey of two days except with her husband or a Dhi-Mahram; -2. "No fasting is permissible on the two days of Id-ul-Fitr and `Id-ul-Adha; -3. "No prayer (may be offered) after the morning compulsory prayer until the sun rises; and no prayer after the `Asr prayer till the sun sets; -4. "One should travel only for visiting three Masjid (Mosques): Masjid-al-Haram (Mecca), Masjid-al- Aqsa (Jerusalem), and this (my) Mosque (at Medina).

Hisham said, "My father said that 'Aishah (ra) used to observe Saum (fast) on the days of Mina." His (i.e., Hisham's) father also used to observe Saum on those days.

That he heard Muawiya bin Abi Sufyan on the day of 'Ashura' during the year he performed the Hajj, saying on the pulpit, "O the people of Medina! Where are your Religious Scholars? I heard Allah's Apostle saying, 'This is the day of 'Ashura'. Allah has not enjoined its fasting on you but I am fasting it. You have the choice either to fast or not to fast (on this day).' "

A bedouin with unkempt hair came to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! Inform me what Allah has made compulsory for me as regards the prayers." He replied: "You have to offer perfectly the five compulsory prayers in a day and night (24 hours), unless you want to pray Nawafil." The bedouin further asked, "Inform me what Allah has made compulsory for me as regards fasting." He replied, "You have to fast during the whole month of Ramadan, unless you want to fast more as Nawafil." The bedouin further asked, "Tell me how much Zakat Allah has enjoined on me." Thus, Allah's Messenger (ﷺ) informed him about all the rules (i.e. fundamentals) of Islam. The bedouin then said, "By Him Who has honored you, I will neither perform any Nawafil nor will I decrease what Allah has enjoined on me. Allah's Messenger (ﷺ) said, "If he is saying the truth, he will succeed (or he will be granted Paradise).

The Prophet (ﷺ) observed the fast on the 10th of Muharram ('Ashura), and ordered (Muslims) to fast on that day, but when the fasting of the month of Ramadan was prescribed, the fasting of the 'Ashura' was abandoned. `Abdullah did not use to fast on that day unless it coincided with his routine fasting by chance.

The Prophet (ﷺ) said, "There is a gate in Paradise called Ar-Raiyan, and those who observe fasts will enter through it on the Day of Resurrection and none except them will enter through it. It will be said, 'Where are those who used to observe fasts?' They will get up, and none except them will enter through it. After their entry the gate will be closed and nobody will enter through it."

Allah's Messenger (ﷺ) said, "When Ramadan begins, the gates of Paradise are opened."

The Prophet (ﷺ) said, "Whoever established prayers on the night of Qadr out of sincere faith and hoping for a reward from Allah, then all his previous sins will be forgiven; and whoever fasts in the month of Ramadan out of sincere faith, and hoping for a reward from Allah, then all his previous sins will be forgiven."

While I was walking with `Abdullah he said, "We were in the company of the Prophet (ﷺ) and he said, 'He who can afford to marry should marry, because it will help him refrain from looking at other women, and save his private parts from committing illegal sexual relation; and he who cannot afford to marry is advised to fast, as fasting will diminish his sexual power."

Allah's Messenger (ﷺ) said, "The month (can be) 29 nights (i.e. days), and do not fast till you see the moon, and if the sky is overcast, then complete Sha'ban as thirty days."

The Prophet (ﷺ) said, "We are an illiterate nation; we neither write, nor know accounts. The month is like this and this, i.e. sometimes of 29 days and sometimes of thirty days."

When the following verses were revealed: 'Eat and drink until the white thread appears to you, distinct from the black thread' and of dawn was not revealed, some people who intended to fast, tied black and white threads to their legs and went on eating till they differentiated between the two. Allah then revealed the words, 'of dawn', and it became clear that meant night and day.

Bilal used to pronounce the Adhan at night, so Allah's Messenger (ﷺ)? said, "Carry on taking your meals (eat and drink) till Ibn Um Maktum pronounces the Adhan, for he does not pronounce it till it is dawn.

The Prophet (ﷺ) said, "If somebody eats or drinks forgetfully then he should complete his fast, for what he has eaten or drunk, has been given to him by Allah."

A man came to the Prophet (ﷺ) and said that he had been burnt (ruined). The Prophet (ﷺ) asked him what was the matter. He replied, "I had sexual intercourse with my wife in Ramadan (while I was fasting)." Then a basket full of dates was brought to the Prophet (ﷺ) and he asked, "Where is the burnt (ruined) man?" He replied, "I am present." The Prophet (ﷺ) told him to give that basket in charity (as expiation).

A man came to the Prophet (ﷺ) and said, "I had sexual intercourse with my wife on Ramadan (while fasting)." The Prophet (ﷺ) asked him, "Can you afford to manumit a slave?" He replied in the negative. The Prophet (ﷺ) asked him, "Can you fast for two successive months?" He replied in the negative. He asked him, "Can you afford to feed sixty poor persons?" He replied in the negative. (Abu Huraira added): Then a basket full of dates was brought to the Prophet (ﷺ) and he said (to that man), "Feed (poor people) with this by way of atonement." He said, "(Should I feed it) to poorer people than we? There is no poorer house than ours between its (Medina's) mountains." The Prophet (ﷺ) said, "Then feed your family with it."

We were in the company of Allah's Messenger (ﷺ) on a journey. He said to a man, "Get down and mix Sawiq (powdered barley) with water for me." The man said, "The sun (has not set yet), O Allah's Messenger (ﷺ)." The Prophet (ﷺ) again said to him, "Get down and mix Sawiq with water for me." The man again said, "O Allah's Messenger (ﷺ)! The sun!" The Prophet (ﷺ) said to him (for the third time) "Get down and mix Sawiq with water for me." The man dismounted and mixed Sawiq with water for him. The Prophet (ﷺ) drank it and then beckoned with his hand (towards the East) and said, "When you see the night falling from this side, then a fasting person should break his fast."
