Sahih al-Bukhari

Allah's Messenger (ﷺ) said, "Whoever died and he ought to have fasted (the missed days of Ramadan) then his guardians must fast on his behalf."

A man came to the Prophet (ﷺ) and said, "O Allah's Messenger (ﷺ)! My mother died and she ought to have fasted one month (for her missed Ramadan). Shall I fast on her behalf?" The Prophet (ﷺ) replied in the affirmative and said, "Allah's debts have more right to be paid." In another narration a woman is reported to have said, "My sister died..." Narrated Ibn `Abbas: A woman said to the Prophet (ﷺ) "My mother died and she had vowed to fast but she didn't fast." In another narration Ibn `Abbas is reported to have said, "A woman said to the Prophet, "My mother died while she ought to have fasted for fifteen days."

Allah's Messenger (ﷺ) 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."

We were in the company of the Prophet (ﷺ) on a journey and he was fasting, and when the sun set, he addressed somebody, "O so-and-so, get up and mix Sawiq with water for us." He replied, "O Allah's Apostle! (Will you wait) till it is evening?" The Prophet (ﷺ) said, "Get down and mix Sawiq with water for us." He replied, "O Allah's Messenger (ﷺ)! (If you wait) till it is evening." The Prophet (ﷺ) said again, "Get down and mix Sawiq with water for us." He replied, "It is still daytime."(1) The Prophet (ﷺ) said again, "Get down and mix Sawiq with water for us." He got down and mixed Sawiq for them. The Prophet (ﷺ) drank it and then said, "When you see night falling from this side, the fasting person should break his fast."

We were traveling with Allah's Messenger (ﷺ) and he was fasting, and when the sun set, he said to (someone), "Get down and mix Sawiq with water for us." He replied, "O Allah's Messenger (ﷺ)! (Will you wait) till it is evening?" The Prophet (ﷺ) again said, "Get down and mix Sawiq with water for us." He replied, "O Allah's Messenger (ﷺ)! It is still daytime." The Prophet (ﷺ) said again, "Get down and mix Sawiq with water for us." So, he got down and carried out that order. The Prophet (ﷺ) then said, "When you see night falling from this side, the fasting person should break his fast," and he beckoned with his finger towards the east.

Allah's Messenger (ﷺ) said, "The people will remain on the right path as long as they hasten the breaking of the fast."

I was with the Prophet (ﷺ) on a journey, and he observed the fast till evening. The Prophet (ﷺ) 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."

Asma bint Abi Bakr said, "We broke our fast during the lifetime of the Prophet (ﷺ) 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."

"The Prophet (ﷺ) sent a messenger to the village of the Ansar in the morning of the day of 'Ashura' (10th of Muharram) to announce: 'Whoever has eaten something should not eat but complete the fast, and whoever is observing the fast should complete it.' "She further said, "Since then we used to fast on that day regularly and also make our boys fast. We used to make toys of wool for the boys and if anyone of them cried for, he was given those toys till it was the time of the breaking of the fast."

The Prophet (ﷺ) said, "Do not practice Al-Wisal (fasting continuously without breaking one's fast in the evening or eating before the following dawn)." The people said to the Prophet, "But you practice Al- Wisal?" The Prophet (ﷺ) replied, "I am not like any of you, for I am given food and drink (by Allah) during the night."

Allah's Messenger (ﷺ) forbade Al-Wisal. The people said (to him), "But you practice it?" He said, "I am not like you, for I am given food and drink by Allah."

That he had heard the Prophet (ﷺ) saying, "Do not fast continuously (practice Al-Wisal), and if you intend to lengthen your fast, then carry it on only till the Suhur (before the following dawn)." The people said to him, "But you practice (Al-Wisal), O Allah's Messenger (ﷺ)!" He replied, "I am not similar to you, for during my sleep I have One Who makes me eat and drink."

Allah's Messenger (ﷺ) forbade Al-Wisal out of mercy to them. They said to him, "But you practice Al- Wisal?" He said, "I am not similar to you, for my Lord gives me food and drink. "

Allah's Messenger (ﷺ) forbade Al-Wisal in fasting. So, one of the Muslims said to him, "But you practice Al- Wisal. O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) replied, "Who amongst you is similar to me? I am given food and drink during my sleep by my Lord." So, when the people refused to stop Al-Wisal (fasting continuously), the Prophet (ﷺ) fasted day and night continuously along with them for a day and then another day and then they saw the crescent moon (of the month of Shawwal). The Prophet (ﷺ) said to them (angrily), "If It (the crescent) had not appeared, I would have made you fast for a longer period." That was as a punishment for them when they refused to stop (practicing Al-Wisal).

The Prophet (ﷺ) said twice, "(O you people) Be cautious! Do not practice Al-Wisal." The people said to him, "But you practice Al-Wisal?" The Prophet (ﷺ) replied, "My Lord gives me food and drink during my sleep. Do that much of deeds which is within your ability."

Allah's Messenger (ﷺ) said, "Do not fast continuously day and night (practice Al-Wisal) and if anyone of you intends to fast continuously day and night, he should continue till the Suhur time." They said, "But you practice Al-Wisal, O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) said, "I am not similar to you;. during my sleep I have One Who makes me eat and drink."

The Prophet (ﷺ) made a bond of brotherhood between Salman and Abu Ad-Darda.' Salman paid a visit to Abu Ad-Darda' and found Um Ad-Darda' dressed in shabby clothes and asked her why she was in that state. She replied, "Your brother Abu Ad-Darda' is not interested in (the luxuries of) this world." In the meantime Abu Ad-Darda' came and prepared a meal for Salman. Salman requested Abu Ad- Darda' to eat (with him), but Abu Ad-Darda' said, "I am fasting." Salman said, "I am not going to eat unless you eat." So, Abu Ad-Darda' ate (with Salman). When it was night and (a part of the night passed), Abu Ad-Darda' got up (to offer the night prayer), but Salman told him to sleep and Abu Ad- Darda' slept. After sometime Abu Ad-Darda' again got up but Salman told him to sleep. When it was the last hours of the night, Salman told him to get up then, and both of them offered the prayer. Salman told Abu Ad-Darda', "Your Lord has a right on you, your soul has a right on you, and your family has a right on you; so you should give the rights of all those who has a right on you." Abu Ad- Darda' came to the Prophet (ﷺ) and narrated the whole story. The Prophet (ﷺ) said, "Salman has spoken the truth."

Allah's Messenger (ﷺ) 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 Messenger (ﷺ) 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 (ﷺ) never fasted in any month more than in the month of Sha'ban. He used to say, "Do those deeds which you can do easily, as Allah will not get tired (of giving rewards) till you get bored and tired (of performing religious deeds)." The most beloved prayer to the Prophet (ﷺ) was the one that was done regularly (throughout the life) even if it were little. And whenever the Prophet (ﷺ) offered a prayer he used to offer it regularly .

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."
