Talhah bin 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 ofEidd, 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 Abu Hurairah: 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 bin al-Madini, a narrator) said: I said to Sufyan: There is a difference of opinion of the name (Abu Muhammad bin Amr). He pondered for a moment and then said: I do not remember except Abu Muhammad bin Amr Sufyan said: A man had come to Kufah after the death of Ismail bin 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 bin 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 bin 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.

Sufyan bin Uyainah said: I saw Sharik who led us in the Asr prayer during a funeral ceremony. He placed his cap in front of him, that is, for saying the obligatory prayer the time of which had come.

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.
