Al-Qasim b. Muhammad said that a man told him he was greatly distressed by wandering thoughts while he was engaged in prayer. He told him to persevere with his prayer, explaining that he would not be free from that till he said when he finished his prayer, “I have not performed my prayer perfectly.” Malik transmitted it.

Ibn ‘Abbas said, “When I was near the age of puberty I came riding on a she-ass and found Allah's Messenger ﷺ leading the people in prayer at Mina with no wall in front of him. I passed in front of part of the row of worshippers, and dismounting, let my she-ass go to pasture and joined the row, and no one objected to that.” (Bukhari and Muslim.)

Abu Huraira reported Allah's Messenger ﷺ 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.

Sahl b. Abu Hathma reported Allah's Messenger ﷺ as saying, “When one of you prays facing a sutra* he should keep close to it and not let the devil interrupt his prayer.” * Sutra (covering, screen) is used of an object a worshipper places in front of him in the direction of the qibla when engaging in prayer. Abu Dawud transmitted it.

Al-Miqdad b. al-Aswad said, “I never saw Allah's Messenger ﷺ praying in front of a stick, a pillar, or a tree, without having it opposite his right or left eyebrow (i.e. side), and not facing it directly.” Abu Dawud transmitted it.

Al-Fadl b. ‘Abbas said, “Allah’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 Allah's Messenger ﷺ 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.

‘A’isha said, “I was sleeping in front of Allah's Messenger ﷺ with my legs between him and the qibla. When he prostrated himself he pinched me and I drew up my legs, and when he stood up I stretched them out.” She added, “At that time there were no lamps in the houses.” (Bukhari and Muslim.)

Abu Huraira reported Allah's Messenger ﷺ 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 Allah's Messenger ﷺ 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.
