‘A'isha said that when God’s messenger intended to engage in private devotion in the mosque he prayed the dawn prayer and then entered his place of seclusion. Abu Dawud and Ibn Majah transmitted it.

She said that the Prophet (ﷺ) used to visit the sick while engaged in a period of private devotion in the mosque and he would pass on straight ahead without pausing and ask for him. Abu Dawud transmitted it.

She said that the sunna for one who is observing a period of private devotion in a mosque is not to visit an invalid, or attend a funeral, or touch or embrace one’s wife, or go out for anything but necessary purposes. There is no period of private devotion in a mosque without fasting, and it must be carried out in a congregational mosque. Abu Dawud transmitted it.

Ibn ‘Umar said that when the Prophet (ﷺ) observed a period of private devotion in the mosque his bedding was placed for him, or a couch was put down for him, behind the column of repentance.* *A column in the Prophet's mosque in Medina, said to have got this name because the repentance of Abu Lubaba was accepted beside it. Ibn Majah transmitted it.

Ibn ‘Abbas reported God’s messenger as saying about one who observes a period of private devotion in a mosque, “He turns away from sins and he is rewarded for good deeds like one who does all good deeds.” Ibn Majah transmitted it.

Abu Huraira reported God’s messenger as saying, "When Ramadan begins the gates of heaven are opened." A version has, "The gates of paradise are opened, the gates of jahannam are locked, and the devils are chained." Another has, "The gates of mercy are opened." (Bukhari and Muslim).

Sahl b. Sa'd reported God’s messenger as saying, "In paradise there are eight gates among which is a gate called ar-Rayyan which only those who fast will enter." (Bukhari and Muslim.)

Abu Huraira reported God's messenger as saying, "He who fasts during Ramadan with faith and seeking his reward from God will have his past sins forgiven; he who prays during the night in Ramadan with faith and seeking his reward from God will have his past sins forgiven; and he who passes Lailat al-qadr in prayer with faith and seeking his reward from God will have his past sins forgiven." (Bukhari and Muslim.)

He reported God’s messenger as saying, "Every deed a son of Adam does will be multiplied, a good deed receiving a tenfold to seven hundredfold reward. God has said, ‘With the exception of fasting, for it is done for my sake and I give a reward for it. One abandons his passion and his food for my sake.* The one who fasts has two occasions of joy, one when he breaks his fast and one when he meets his Lord. The bad breath of one who fasts is sweeter to God than the fragrance of musk. Fasting is a protection, [i.e. from acts of disobedience in this world and from hell in the next. Pt. vi.] and when the day of the fast of any of you comes he must not use vile language or raise his voice, and if anyone reviles him or tries to fight with him he should tell him he is fasting.” *This is not from the Qur’an, but is a hadith qudsi, a tradition which gives words spoken by God. (Bukhari and Muslim.)

Ibn ‘Umar reported God’s messenger as saying, “Do not fast till you see the new moon, and do not break your fast till you see it; but if the weather is cloudy calculate when it should appear.” In a version he said, “The month consists of twenty-nine days, but do not fast till you see it, and if the weather is cloudy wait till thirty days of the previous month have passed.” (Bukhari and Muslim.)

Abu Huraira reported God’s messenger as saying, “Fast when you see it and break your fast when you see it, and if the weather is cloudy treat Sha‘ban as having thirty days.” (Bukhari and Muslim.)

Ibn ‘Umar reported God’s messenger as saying, “We are an unlettered people who can neither write nor count. The month is thus and thus and thus,” drawing in his thumb when he said it the third time.* Then he said, “The month is thus and thus and thus,” meaning a complete thirty days. He meant alternately twenty-nine and thirty. *Spreading out the ten fingers the first two times and nine the third time. (Bukhari and Muslim.)

Abu Bakra reported God’s messenger as saying, “The months of festival, Ramadan and Dhul-hijja, are not defective.”* *The most probable meaning is that, even if these months have only twenty-nine days, they are not on that account to be considered deficient in comparison with a month which has thirty days. (Bukhari and Muslim.)

Abu Huraira reported God’s messenger as saying, “None of you must fast one day or two days just before Ramadan, except in the case of a man who has been in the habit of observing a particular fast, for he may fast on that day.”* *If a man is in the habit of fasting on a particular day of the week and one or other of the two days before Ramadan falls on that day, he may observe his usual practice. (Bukhari and Muslim.)

Anas reported God's messenger as saying, “Take a meal a little before dawn, for there is a blessing in taking a meal at that time.” (Bukhari and Muslim.)

Sahl reported God’s messenger as saying, “The people will continue to prosper as long as they hasten the breaking of the fast.”* *This refers to each day during Ramadan, and recommends that the fast should be broken as early as that may lawfully be done. (Bukhari and Muslim.)

‘Umar reported God’s messenger as saying, “When the night approaches on this side and the day retreats on that side and the sun sets, he who fasts has reached the time to break it.” (Bukhari and Muslim.)

Abu Huraira said that God’s messenger forbade uninterrupted fasting, and when a man said, “You fast uninterruptedly, messenger of God,” he replied, “Which of you is like me? During the night my Lord gives me food and drink.” (Bukhari and Muslim.)

‘A'isha said, “God’s messenger used to kiss and embrace while he was fasting, but he was the one of you who had most control over his desire.” (Bukhari and Muslim.)

She said that God’s messenger would be overtaken by the dawn in Ramadan when he was in a state of sexual defilement, not owing to a dream, and would wash and fast. (Bukhari and Muslim.)
