Abu Huraira reported Allah's Messenger ﷺ as saying, "Men will continue to question one another till this is propounded

‘Ata’ b. Yasar reported Allah's Messenger ﷺ as saying, “O Allah, do not let my grave become an idol which is worshipped. Allah’s anger is severe against people who take the graves of their prophets as mosques.” Malik transmitted it in mursal form.

Mu'adh b. Jabal said that the Prophet (ﷺ) used to like to pray in al-hitan*. One of its transmitters says that it means gardens. * I have given the Arabic word because it is explained in the text. Why it should need to be explained is not clear. Tirmidhi transmitted it and said, “This is a gharib tradition which we know only among the traditions of al-Hasan b. Abu Ja'far whom Yahya b. Sa'id and others have declared to be weak.”

Anas b. Malik reported Allah's Messenger ﷺ 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 Allah's Messenger ﷺ 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 Allah's Messenger ﷺ 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 Allah's Messenger ﷺ as saying, “None of you must pray in a single garment of which no part comes over his shoulders.” (Bukhari and Muslim.)

He said that he heard Allah's Messenger ﷺ say, “If anyone prays in a single garment he should cross the two ends.” Bukhari transmitted it.

‘A’isha said that Allah's Messenger ﷺ 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.”

Anas said that ‘A’isha had a figured curtain with which she secluded the side of her house, but the Prophet (ﷺ) said to her, “Remove this figured curtain of yours from us, for its pictures keep interfering with my prayer.” Bukhari transmitted it.

‘Uqba b. ‘Amir said that Allah's Messenger ﷺ 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.)
