Sayyiduna Abu Hurairah رضي الله عنه narrates from the Noble Prophet صلى الله عليه وسلم that he صلى الله عليه وسلم said: "Something equal to the back stick of a camel saddle is sufficient as a sutrah, even if it is as thin as a hair." Imam Abu Bakr رحمه الله says that I fear Muhammad bin Qasim made a mistake in narrating this as a marfu' (attributed to the Prophet). Imam Abu Bakr رحمه الله says that from the ahadith of the Noble Prophet صلى الله عليه وسلم, there is strong evidence that he صلى الله عليه وسلم intended the length of the back stick of a camel saddle (for the sutrah), not its width. Among these narrations of the Noble Prophet صلى الله عليه وسلم is that a spear would be planted for him صلى الله عليه وسلم and he صلى الله عليه وسلم would use it as a sutrah while praying, and the width of a spear is not like the width of the back stick of a camel saddle.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that I saw the Messenger of Allah (peace and blessings of Allah be upon him) performing prayer in the Eid ground, taking a spear as a sutrah. Imam Abu Bakr (may Allah have mercy on him) says that from the command of the Prophet (peace and blessings of Allah be upon him) to use an arrow as a sutrah in prayer, it becomes clear and established that in the command to use the rear wooden part of a saddle as a sutrah, what the Prophet (peace and blessings of Allah be upon him) meant was its length, not both its length and width.

Hazrat Abdul Malik bin Abdul Aziz narrates from his father, and he from his grandfather, that the Messenger of Allah (peace be upon him) said: "Make a sutrah in your prayers, even if it is with an arrow."

Abu Hurairah (may Allah be pleased with him) narrates that Abu al-Qasim (peace and blessings be upon him) said: "When any one of you prays, he should place something in front of him." And on one occasion he said: "He should place something in front of his face. If he does not find anything, then he should plant a stick. And if even a stick is not available, then he should draw a line. Then nothing that passes in front of him will harm him." Muhammad bin Mansur al-Jawaz narrated these words: "He should place something in front of his face." The rest of the narration is like the previous narration.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates from the Messenger of Allah (peace and blessings of Allah be upon him) that he said, Imam Abu Bakr (may Allah have mercy on him) says, but the authentic narration is the one that Bishr bin Mufaddal has narrated, Mu'ammar and Thawri have also narrated from 'Amr bin Harith in the same way, but both of them have narrated from the father of 'Amr bin Harith instead of his grandfather.

And the explanation of the evidence that it is better to stand for a long time waiting for the praying person to finish his prayer rather than passing in front of him.

Hazrat Basar bin Saeed narrates that Zaid bin Khalid sent me to Hazrat Abu Juhaim (may Allah be pleased with him) to ask what sin is incurred by a person who passes in front of someone performing prayer. He replied that if he were to stand for forty (years or days), it would be better for him than passing in front of the one praying.

Imam Sahib narrates from his two respected teachers, Ahmad bin Mani’ and Muhammad bin Rafi’, with their chain of transmission, from Sayyiduna Abu Hurairah (may Allah be pleased with him), who reports that the Messenger of Allah (peace and blessings be upon him) said:“If any one of you were to realize the sin of passing in front of his brother from the width while he is supplicating to his Lord, then it would be better for him to stand in that place for a hundred years than to take even a single step.”This is the narration of Ibn Mani’.

That is when the person praying is performing the prayer with a sutrah placed. And when the person praying is performing the prayer without a sutrah, then it is permissible to pass in front of the person praying.

Sayyiduna Mutlib bin Abi Wada'ah (may Allah be pleased with him) narrates that I saw the Messenger of Allah (peace and blessings be upon him) when he finished his Tawaf, he came to the edge of the Mataf and offered two rak'ahs of prayer, while there was no one between him and those performing Tawaf.
