Abu Qatada reported God’s Messenger as saying, “When one of you enters the mosque he should pray two rak'as before sitting down.” (Bukhari and Muslim.)

Ka'b b. Malik said that the Prophet (ﷺ) always came back from a journey by day in the forenoon, and when he arrived he went first to the mosque, and having prayed two rak'as in it he sat down in it. (Bukhari and Muslim.)

Jabir reported God’s Messenger as saying, “If anyone eats of this offensive tree* he must not approach our mosque, for the angels are harmed by the same things as men.” * Bukhari At’ima, 49, shows the Prophet’s objection to onions and garlic. One of these may be meant here. (Bukhari and Muslim.)

Anas reported God's Messenger as saying, “Spitting in the mosque is a sin which is expiated by burying the spittle.” (Bukhari and Muslim.)

Abu Huraira reported God’s Messenger as saying, “When one of you gets up for prayer he must not spit in front, of him, because he is holding intimate converse with God as long as he is in his place of prayer; nor must he spit towards his right, for there is an angel at his right; but he may spit towards his left or under his feet and bury it.” The version of Abu Sa'id has “under his left foot.” (Bukhari and Muslim.)

‘A’isha told of God's Messenger as saying in his illness from which he did not recover, “God curse the Jews and Christians! They have taken the graves of their prophets as mosques.” (Bukhari and Muslim.)

Ibn ‘Umar reported God’s Messenger as saying, “Perform some of your prayer in your houses, and do not turn them into graves.”* * This is most probably a figurative expression indicating that a house in which prayer is not offered is like a grave, as God is not worshipped there. (Bukhari and Muslim.)

Abu Sa'id al-Khudri reported God’s Messenger as saying, “When you see a man frequenting the mosque, testify that he has faith, for God says, ‘God’s mosques are visited only by those who believe in God and the last day.”* * Al-Qur'an; 9:18 Tirmidhi, Ibn Majah and Darimi transmitted it.

‘Abd ar-Rahman b. ‘A’ish reported God’s Messenger as saying: I saw my Lord in the most beautiful form, and He said, "What do the angels near My presence dispute about?" I replied," Thou knowest best.” Then He placed the palm of His hand between my shoulder-blades and I felt the coolness of it between my nipples! Then I knew what was in the heavens and the earth. And he recited, "Thus did We show Abraham the kingdom of the heavens and the earth, and it was so that he might have certainty (Al-Qur’an; 6:75).’’ Darimi transmitted it in mursal form.

Tirmidhi has something similar from ‘Abd ar-Rahman, and from Ibn ‘Abbas and Mu'adh b. Jabal, in which he had additions: He asked, "Muhammad, do you know what the angels near My presence dispute about?" I replied, "Yes, about expiations, and they are remaining in the mosques after the prayers are over, walking on foot to the congregational prayers, and performing elaborate ablution in unpleasant circumstances (Cf. p. 151). Whoever does that will live and die righteously, and as far as his sin is concerned, he will be as he was on the day his mother gave birth to him." He said, "Muhammad, when you pray say, ‘O God, I ask Thee to enable me to do good deeds, abandon objectionable things, and love the poor, and when Thou intendest to test Thy servants, take me to Thyself without being led astray.'" He said, "People are raised in degree by saluting all and sundry, providing food, and praying at night when people are asleep." The wording of this tradition is as it occurs in al-Masabih, but I found it traced to ‘Abd ar-Rahman only in Sharh as-sunna.

Hakim b. Hizam said that God's Messenger prohibited retaliation being taken in a mosque, the recitation of poems in it, and the infliction of punishment in it. Abu Dawud in his Sunan and the author of Jami‘ al-usul ( Ibn al-Athir) in his work transmitted it from Hakim, but in al-Masabih it is transmitted from Jabir.

Mu'adh b. Jabal said: God’s Messenger was detained one morning from observing the prayer with us till the sun had almost appeared over the horizon. He then came cut quickly, and when the iqama had been uttered he conducted the prayer in a shortened form; then when he had given the salutation he called out to us saying, “Keep to your rows as you were.” Then turning to us he said, “I shall tell you what detained me from you this morning. I got up during the night, performed ablution, and prayed what I could; but during my prayer I dozed and was overcome, and there and then I saw my Lord in the most beautiful form. He addressed me by name, and when I replied, ‘At Thy service, my Lord,’ He asked, ‘What do the angels near My presence dispute about?’ and I replied that I did not know. He asked it three times. Then I saw Him put the palm of His hand between my shoulder-blades, so that I experienced the coolness of His fingers between my nipples so everything became clear to me and I attained knowledge. He then addressed me by name, and when I replied, ‘At Thy service, my Lord,’ He asked, ‘What do the angels near My presence dispute about?’ I replied, ‘Expiation.’ He asked what they were, and I replied, ‘Walking on foot to the congregational prayers, sitting in the mosques after the prayers are over, and performing complete ablution in difficult circumstances. He asked what next they disputed about, and when I said it was about degrees, He asked what they were and I replied, ‘Providing food, speaking gently, and praying at night when people are asleep.’ He then told me to make a request, and I said, ‘O God, I ask Thee for power to do good things and abandon objectionable things, for love towards the poor, that Thou shouldest forgive me and show mercy to me, and that when Thou intendest to test any people Thou wilt take me to Thyself without being led astray. And I ask for Thy love, the love of those who love Thee, and a love of doing things which will bring me near to Thy love.’” Then God’s Messenger said, “It is true, so study it and learn it.” Ahmad and Tirmidhi transmitted it, and Tirmidhi said, “This is a hasan sahih tradition. I asked Muhammad b. Isma'il (Al-Bukhari) about this tradition, and he said it is a sahih tradition.”

Anas b. Malik reported God’s Messenger as saying, “A man’s prayer in his house is equivalent to a single observance of prayer, his prayer in a tribal mosque is equivalent to twenty-five, his prayer in a mosque in which the Friday prayer is observed is equivalent to five hundred, his prayer in the Aqsa mosque is equivalent to fifty thousand, his prayer in my mosque is equivalent to fifty thousand, and his prayer in the sacred mosque (the Ka’ba) is equivalent to a hundred thousand.” Ibn Majah transmitted it.

Abu Dharr said that he asked God’s Messenger which mosque was set up first in the earth and was told that it was the sacred mosque. He asked which came next and was told that it was the Aqsa mosque. He asked how long a space of time separated their building and the Prophet (ﷺ) told him it was forty years, adding, “Then the earth is a mosque for you, so pray wherever you are at the time of prayer.” (Bukhari and Muslim.)

“Umar b. Abu Salama said that he saw God’s Messenger praying in Umm Salama’s house girded with a single garment, placing its two ends over his shoulders.* * This is explained as meaning that the ends were each over a shoulder and under the other armpit and tied over the chest. (Bukhari and Muslim.)

Abu Huraira reported God’s Messenger as saying, “None of you must pray in a single garment of which no part comes over his shoulders.” (Bukhari and Muslim.)

‘A’isha said that God’s Messenger prayed in a woollen garment of hers with markings, and he gave a look at the markings. When he had finished he said, “Take this woollen garment of mine to Abu Jahm and bring me Abu Jahm’s Anbijani* garment, for it has distracted me just now from my prayer.” * A type of garment from the Syrian town of Manbij. The word in the text is anbijaniya. Manbijaniya is perhaps more common. See Lane, Lexicon, p. 2755 Pt. III (Bukhari and Muslim.) In a version by Bukhari he said, “I was looking at its markings while I was engaged in prayer, and I am afraid lest it may beguile me.”

‘Uqba b. ‘Amir said that God’s Messenger was presented with a silk gown which he put on and wore while praying. Then when he withdrew he pulled it off vigorously as though he disapproved of it, saying, “This is not fitting for the pious.” (Bukhari and Muslim.)

‘A’isha reported God’s Messenger as saying, “The prayer of a woman who has reached puberty is not accepted unless she is wearing a veil.”* * A veil (khimar) covering the head and the breasts. Cf. Al-Quran; 24:31. Abu Dawud and Tirmidhi transmitted it.

Shaddad b. Aus reported God’s Messenger as saying, “Act differently from the Jews, for they do not pray in their sandals or their shoes.”* * Khuff (pl. khifaf), an article of footwear which came up above the ankle. Traditions tell that the Prophet (ﷺ) allowed pilgrims to wear the khuff only when unable to procure sandals, but said they must be cut to come below the ankle. Cf. Bukhari, Hajj, 21, 23; Libas, 8, 4, 15, 73. Abu Dawud transmitted it.
