Abu Sa'id al-Khudri said: 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 (ﷺ) 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 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.

Ibn ‘Umar said that the Prophet (ﷺ) would go out in the morning* to the place of prayer with a staff in front of him which was carried and set up in front of him in the place of prayer, and he would pray in its direction. * i.e. on the day of the 'Id. Bukhari transmitted it.

Talha b. ‘Ubaidallah reported God’s Messenger as saying, “When one of you places in front of him something such as the back of a saddle, he should pray without caring who passes on the other side of it.” Muslim transmitted it.

Abu Sa'id reported God’s Messenger as saying, “When one of you prays facing something which conceals him from people and someone wishes to pass in front of him, he should turn away; but if he refuses to go, he should turn him away forcibly, for he is only a devil.” This is Bukhari’s wording, and Muslim has something to the same effect.

Abu Huraira reported God’s Messenger as saying, “A woman, an ass and a dog cut off the prayer, but something like the back of a saddle guards against that.” Muslim transmitted it.

Abu Huraira reported God’s Messenger as saying, “When one of your prays he should put something in front of his face, and if he can find nothing he should set up his stick; but if he has no stick with him he should draw a line, then what passes in front of him will not harm him.” Abu Dawud and Ibn Majah transmitted it.

Al-Fadl b. ‘Abbas said, “God’s Messenger came to us accompanied by ‘Abbas when we were in open country belonging to us. He prayed in a desert with no sutra in front of him, and a she-ass and a bitch of ours were playing in front of him, but he paid no attention to that.” Abu Dawud transmitted it and Nasa’i has something similar.

Abu Sa'id reported God’s Messenger as saying, “Nothing interrupts prayer, but repulse, as much as you can anyone who passes in front of you, for he is just a devil.” Abu Dawud transmitted it.

Abu Huraira reported God’s Messenger as saying, “If one of you knew what he incurred by passing in front of his brother and interfering with his prayer, it would be better for him to stop a hundred years than to take a single step.” Ibn Majah transmitted it.

Ka‘b al-Ahbar said, “If one who passes in front of a man who is praying knew what was laid to his charge, it would be better for him to be swallowed up by the earth than to pass in front of him.” A version has “less serious for him.” Malik transmitted it.

Ibn ‘Abbas reported God’s Messenger as saying, “When one of you prays without a sutra, an ass, a pig, a Jew, a Magian, and a woman cut off his prayer, but it will suffice if they pass in front of him at a distance of over a stone’s throw.” Abu Dawud transmitted it.

Abu Humaid as-Sa'idi said among a company of the companions of God’s Messenger, “I am the one among you who is best versed in the way God’s Messenger prayed. I saw that when he uttered the takbir he placed his hands opposite his shoulders; when he bowed he rested his hands on his knees, then bent his back; when he raised his head he stood erect with his spine straight; when he prostrated himself he placed his arms so that they were not spread out, and the fingers were not drawn in, and the points of his toes were facing the qibla; when he sat up at the end of two rak'as he sat on his left foot and raised the right; and when he sat up after the last rak'a he put forward the left foot, raised the other, and sat on his hips.” Bukhari transmitted it.

Nafi‘ said that when Ibn ‘Umar began prayer he said the takbir and raised his hands; when he bowed he raised his hands; when he said, “God listens to him who praises Him” he raised his hands; and when he got up at the end of two rak'as he raised his hands. Ibn ‘Umar traced that back to the Prophet. Bukhari transmitted it.

He said that he saw the Prophet (ﷺ) praying, and when he had prayed an odd number of rak'as he did not stand up till after he had adopted a sitting position. Bukhari transmitted it.

Wa’il b. Hujr said that he saw the Prophet (ﷺ) raise his hands when he began prayer. He said the takbir, then pulled his garment round him, then placed his right hand on his left. When he was about to bow he took his hands out of his garment, and after he had raised (them and said the takbir he bowed. When he said, “God listens to him who praises Him” he raised his hands, and when he prostrated himself he did it between his hands. Muslim transmitted it.
