Sunan Ibn Majah

"The people will remain upon goodness so long as they hasten to break the fast. Hasten to break the fast, for the Jews delay it."

"When any one of you breaks his fast, let him break it with dates. If he cannot find dates, then let him break it with water, for it is a means of purification."

"There is no fast for the one who did not make it incumbent upon himself from the night before."

“The Messenger of Allah (ﷺ) would enter upon me and say: ‘Do you have anything (any food)?’ If we said: ‘No,’ he would say: ‘Then I am fasting.’ So he would continue fasting, then it we were given some food, he would break his fast.” She said: “Sometimes he would fast and (then) break fast (i.e., combine fasting and breaking fast in one day).” I said: “How is that?” She said: “Like the one who goes out with charity (i.e., something to give in charity),and he gives some away and keeps some.”

“I heard Abu hurairah say: ‘No, by the Lord of the Ka’bah! I did not say: “Whoever wakes up in a state of sexual impurity (and wants to fast) then he must not fast.” Muhammad (ﷺ) said it.’”

“The Prophet (ﷺ) used to spend the night in a state of sexual impurity, then Bilal would come to him and inform him that it is time for prayer. So he would get up and have a bath, and I would see the water dripping from his head, then he would go out and I would hear his voice during Fajr prayer.” (One of the narrators) Mutarrif said: "I said to Amir: 'Was that during Ramadan?' He said: 'In Ramadan and at other times.'"

“I asked Umm Salamah about a man who gets up in the morning when he is in a state of sexual impurity and wants to fast. She said: “The Messenger of Allah (ﷺ) used to get up in the morning in a state of sexual impurity after having intercourse, not from a wet dream, then he would take a bath and complete his fast.’”

“The Prophet (ﷺ) said: ‘Whoever fasts continually, he neither fasts nor breaks his fast.’”

“There is no fasting for one who fasts continually.”

The Messenger of Allah (ﷺ) used to enjoin fasting the bright days – the thirteenth, fourteenth and fifteenth (when the moon is full). He said: “It is like fasting for a lifetime.” Another chain from 'Abdul-Malik bin Qatadah bin Malhan Al-Qaisi, from his father, from the Prophet (ﷺ) with similar wording. Ibn Majah said: Shu'bah erred (in the name of one of the narrators)and Hammam was correct.

“Whoever fasts three days in every month, that is fasting for a lifetime.” Then, in testimony of that, Allah revealed: “Whoever brings a good deed shall have ten time the like thereof to his credit.” So one day is equivalent to ten (in reward).

“The Messenger of Allah (ﷺ) used to fast three days of each month.” I said: “Which were they?” She said: “He did not care which days they were.”

“I asked ‘Aishah about the fasting of the Prophet (ﷺ). She said: ‘He used to fast until we thought he would always fast. And he used to not fast until we thought he would always not fast. I never saw him fast more in any month than in Sha’ban. He used to fast all of Sha’ban; he used to fast all of Sha’ban except a little.’”

“The Messenger of Allah (ﷺ) used to fast until we thought he would never stop fasting. And he used to not fast until we thought we would never fast. And he never fasted any complete month apart from Ramadan, from the time he came to Al- Madinah.”

“The most beloved fast to Allah is the fast of Dawud, for he used to fast one day and not the next. And the most beloved of prayer to Allah is the prayer of Dawud; he used to sleep half of the night, pray one-third of the night and sleep one-sixth of the night.”

“Umar bin Khattab said: ‘O Messenger of Allah! What about a person who fasts two days and does not fast one day?’ He said: ‘Is anyone able to do that?’ He said: ‘O Messenger of Allah! What about a person who fasts one day and not the next?’ He said: ‘That is the fast of Dawud.’ He said: ‘What about a man who fasts one day and does not fast the next two days?’ He said: ‘I wish that I were given the ability to do that.’”

“I heard the Messenger of Allah (ﷺ) say: ‘(Prophet) Nuh fasted for a lifetime, except for the Day of Fitr and the Day of Adha.’”

“Whoever fasts six days after the Fitr will have completed the year, for whoever does a good deed will have the reward of ten like it.”

“Whoever fasts Ramadan then follows it with six days of Shawwal, it is as if he fasted for a lifetime.”

“Whoever fasts one day in the cause of Allah, Allah will keep the Fire away from his face the distance of seventy autumns (years) for that day.”
