Talhah b. 'Ubaid Allah reported the Messenger of Allah (ﷺ) as saying: When you place in front of you something such as the back of a saddle, then there is no harm if someone passes in front of you (i.e. the other side of it).

'Ata said: The back of the saddle is (about) one cubit (in height) or more than that.

Ibn 'Umar said: When the Messenger of Allah (ﷺ) would go out (for prayer) on the day of 'Id, he ordered to bring a lance, it was then setup in front of him and he would pray in its direction, and the people (stood) behind him. He used to do so during journey ; hence the rulers would take it (lance with them).

Abu Juhaifah said: The Prophet (ﷺ) led them in prayer at al-Batha', with a staff set up in front of him. (He prayed) two rak'ahs of the Zuhr prayer and two rak'ahs of the 'Asr prayer. The women and the donkeys would pass in front of the staff.

Narrated AbuHurayrah: The Prophet (ﷺ) said: When one of you prays, he should put something in front of his face, and if he can find nothing , he should set up his staff; but if he has no staff, he should draw a line; then what passes in front of him will not harm him.

This tradition has also been reported by Abu Hurairah through a different chain of narrators. Abu Hurairah reported: The Prophet (ﷺ) said: ...... He then narrated the tradition about drawing the line. Sufyan said: We did not find anything by which we could reinforce this tradition, and this has been narrated only through this chain. He ('Ali b. al-Madini, a narrator) said: I said to Sufyan: There is a difference of opinion of the name (Abu Muhammad b. 'Amr). He pondered for a moment and then said: I do not remember except Abu Muhammad b. 'Amr Sufyan said: A man had come to Kufah after the death of Isma'il b. Umayyah ; he was seeking Abu Muhammad until he found him. He asked him (about this tradition) but he became confused. Abu Dawud said: I heard Ahmad b. Hanbal who was questioned many times how the line should be drawn. He replied: In this way. horizontally like crescent. Abu Dawud said: I heard Musaddad say: Ibn Dawud said: The line should be drawn perpendicularly. Abu Dawud said: I heard Ahmad b. Hanbal describing many times how the line should be drawn. He said: In this way horizontally in the round semi-circular form like the crescent, that is (the line should be) a curve.

Ibn 'Umar said: The Prophet (ﷺ) used to pray facing his camel.

Narrated Al-Miqdad ibn al-Aswad: I never saw the Messenger of Allah (ﷺ) praying in front of a stick, a pillar, or a tree, without having it opposite his right or left eyebrow, and not facing it directly.

Narrated Abdullah ibn Abbas: The Prophet (ﷺ) said: Do not pray behind a sleeping or a talking person.

Narrated Sahl ibn AbuHathmah: The Prophet (ﷺ) said: When one of you prays facing a sutrah he should keep close to it, and not let the devil interrupt his prayer. Abu Dawud said: This tradition has also been narrated by Waqid b. Muhammad from Safwan from Muhammad b. Sahl on the authority of his father, or on the authority of Muhammad b. Sahl from the Prophet (ﷺ). Some have narrated it from Nafi' b. Jubair on the authority of Sahl b. Sa'd. There is a variation in the chain of its narrators.

Sahl said: The distance between the place where the Prophet (ﷺ) stood and the qiblah (i.e. the sutrah or the wall of the mosque) was as much as to allow a goat to pass.

Abu Sa'id al-Khudri reported the Messenger of Allah (ﷺ) as saying: When one of you prays, he should not let anyone pass in front of him; he should turn him away as far as possible; but if he refuses (to go), he should fight him, for he is only a devil.

Abu Sa'id al-Khudri reported the Messenger of Allah (ﷺ) as saying: When one of you prays, he should pray facing the sutrah (screen or covering) and he should keep himself close to it. He then narrated the tradition to the same effect.

Abu 'Ubaid said: I saw 'Ata b. Yazid al-Laithi praying in a standing posture. So I went to him passing in front of him; he, therefore, turned me away. He then said to me: Abu Sa'id al-Khudri reported the Messenger of Allah (ﷺ) as saying: If anyone of you can do that he should not let anyone pass between him and the qiblah, he should do it.

Abu Salih said: I narrate what I witnesses from Abu Sa'id and heard from him. Abu Sa'id entered upon Marwan and said: I heard the Messenger of Allah (ﷺ) say: When one of you prays facing any object which conceals him from people, and someone wishes to pass in front of him, he should strike him at his chest; if he refuses (to go), he should fight him; he is only a devil. Abu Dawud said: Sufyan Ath-Thawri said: "A person arrogantly walks in front of me while I am praying, so I stop him, and a weak person passes, so I dont stop him."

Narrated Abu Juhaim : The Messenger of Allah(ﷺ) as saying: "If one who passes in front of a man who is praying knew the responsibility he incurs, he would prefer to stand still for forty. . . rather than pass in front of him. Abu al-Nadr said: I do not know whether he said forty days, or months, or years." Abu Dawud: Sufyan al-Thawri said: If a man passes proudly in front of me while I am praying, I shall stop him, and if a weak man passes, I shall not stop him.

Hafs reported that the Messenger of Allah(ﷺ) as saying, and the other version of this tradition transmitted through a different chain has: Abu Dharr said (and not the Prophet): If there is not anything like the back of a saddle in front of a man who is praying, then a donkey, a black dog, and a woman cut off his prayer. I asked him: Why has the black dog been specified, distinguishing it from a red, a yellow and a white dog? He replied: My nephew, I also asked the Messenger of Allah(ﷺ) the same question as you asked me. He said: The black dog is a devil.

Narrated Abdullah ibn Abbas: Qatadah said: I heard Jabir ibn Zayd who reported on the authority of Ibn Abbas; and Shu'bah reported the Prophet (ﷺ) as saying: A menstruating woman and a dog cut off the prayer. Abu Dawud said: Sa'id, Hisham and Hammam narrated this tradition from Qatadah on the authority of Jabir b. Zaid as a statement of Ibn 'Abbas.

Narrated Abdullah ibn Abbas: Ikrimah reported on the authority of Ibn Abbas, saying: I think the Messenger of Allah (ﷺ) said: When one of you prays without a sutrah, a dog, 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 said: There is something about this tradition in my heart. I used to discuss it with Ibrahim and others. I did not find anyone who narrated it from Hisham and knew it. I did not know anyone who reported it from Hisham and knew it. I did not know anyone who related it from Hisham. I think the confusion is on the part of Ibn Abi Saminah that is, Muhammad b. Isma'il al-Basri, the freed slave of Banu Hisham. In this tradition the mention of words "a Magian" is rejected; the mention of the words "at a stone's throw" and "a pig" is rejected. Abu Dawud said: I did not hear this tradition except from Muhammad b. Isma'il b. Samurrah and I think he was mistaken because he used to narrate to us from his memory.

Yazid b. Namran said: I saw a crippled man at Tabuk. He (the man) said: I passed riding a donkey in front of the Prophet(ﷺ) who was praying. He said (cursing him): O Allah, cut off his walking. Thenceforth I could not walk.
