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 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.)

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

‘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.”

Anas said that ‘A’isha had a figured curtain with which she secluded the side of her house, but the Prophet 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 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.)

Salama b. al-Akwa‘said that he told God’s Messenger he was a man who went out hunting, and asked whether he might pray in a single shirt. He replied, “Yes, but fasten it, even if it should be with a thorn.” Abu Dawud transmitted it and Nasa’i transmitted something similar.

Abu Huraira said that while a man was praying letting his lower garment trail, God’s Messenger said to him, “Go and perform ablution.” After he had gone to perform ablution and returned a man asked God’s Messenger why he had ordered him to perform ablution, and he said “He was praying with his lower garment trailing, and God does not accept the prayer of a man who lets his lower garment trail.” Abu Dawud transmitted it.

‘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.

Umm Salama said that she asked God's Messenger whether a woman might pray in a shift and veil without wearing a lower garment. He replied, “If the shift is ample and covers the surface of her feet.” Abu Dawud transmitted it and he mentioned a number who did not trace it beyond Umm Salama.

Abu Huraira said that God’s Messenger forbade trailing garments during prayer and that a man should cover his mouth. 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 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.

While God’s Messenger was leading his companions in prayer he took off his sandals and laid them at his left side; so when the people saw that, they removed their sandals. When he had finished his prayer he asked, "What made you remove your sandals? They replied, “We saw you remove yours, so we removed ours.” God’s Messenger then said, “Gabriel came to me and informed me that there was filth on them. When any of you comes to the mosque he should examine, and if he sees filth on his sandals he should wipe it off and pray in them.” Abu Dawud and Darimi transmitted it.

Abu Huraira reported God’s Messenger as saying, “When any of you prays he should not place his sandals at his right or at his left so as to be at the right of someone else, unless no one is at his left, but should place them between his feet.” A version has, “or pray with them on.” Abu Dawud transmitted it and Ibn Majah transmitted something to the same effect.

Abu Sa'id al-Khudri said, “I visited the Prophet and saw him praying on a reed mat on which he was prostrating himself.” He said, “And I saw him praying in a single garment with part over his shoulder.” Muslim transmitted it.

‘Amr b. Shu'aib, on his father's authority, said that his grandfather declared he had seen God’s Messenger praying both barefoot and wearing sandals. Abu Dawud transmitted it.

Muhammad b. al-Munkadir said that Jabir led them in prayer in [his] lower garment which he had tied at the nape of his neck, his clothes being placed on the clothes-stand. Someone said to him, “You are praying in a single garment.” He replied, “I did that only that a fool like you might see me. Which of us had two garments in the time of God’s Messenger?” Bukhari transmitted it.

Ubayy b. Ka'b said, “Prayer in a single garment was a practice we followed along with God’s Messenger, and no blame was cast on us.” Ibn Mas'ud said, “That was only when clothing was scarce, but when God enlarged our circumstances prayer in two garments became purer.” Ahmad transmitted it.
