Sunan Ibn Majah

“When anyone of you performs prayer, let him put something in front of him. If he cannot find anything then let him put a stick. If he cannot find one, then let him draw a line. Then it will not matter if anything passes in front of him.”

“They sent me to Zaid bin Khalid to ask him about passing in front of one who is performing prayer. He told me that the Prophet (ﷺ) said: ‘Waiting for forty is better than passing in front of one who is performing prayer.’” (One of the narrators) Sufyan said: "I do not know if he meant forty years, months, days, or hours."

“What did you hear from the Prophet (ﷺ) about a man when he is performing prayer?” He said: “I heard the Prophet (ﷺ) saying: ‘If anyone of you knew (how great is the sin involved) when he passed in front of his brother who is performing prayer, then waiting for forty’,” (one of the narrators) said: “I do not know if he meant forty years, forty months, or forty days, ‘would be better for him than that.”

“The Prophet (ﷺ) said: ‘If anyone of you knew (how great is the sin involved) in passing in front of his brother while he is performing prayer, waiting for one hundred years would be better for him than one step that he takes.’”

“The Prophet (ﷺ) was performing prayer at ‘Arafat, and Fadl and I came riding a female donkey. We passed in front of part of the row, then we dismounted and left the donkey, and we came and joined the row.”

“The Prophet (ﷺ) was performing prayer in the house of Umm Salamah, and ‘Abdullah or ‘Umar bin Abu Salamah passed in front of him; he gestured his hand, and he went back. Then Zainab bint Umm Salamah passed in front of him, and he gestured his hand, but she kept going. When the Messenger of Allah (ﷺ) finished his prayer, he said: ‘These (women) are more stubborn.’”

“The prayer is severed by a black dog and a woman who has reached the age of menstruation.”

“The prayer is severed by a woman, a dog and a donkey.”

“The prayer is severed by a woman, a dog and a donkey.”

“The prayer is severed by a woman, a donkey, and a black dog, if there is not something like the handle of a saddle in front of a man.” I (‘Abdullah) said: “What is wrong with a black dog and not a red one?” He (Abu Dharr) said: ‘I asked the Messenger of Allah (ﷺ) the same question, and he said: “The black dog is a Shaitan (satan).”

‘Mention was made in the presence of Ibn ‘Abbas about what severs the prayer. They mentioned a dog, a donkey and a woman. He said: ‘What do you say about kids (young goats)? The Messenger of Allah (ﷺ) was performing prayer one day, when a kid came and wanted to pass in front of him. The Messenger of Allah (ﷺ) preceded it toward the Qiblah. (to tighten the space and prevent it from passing in front of him).’”

“The Messenger of Allah (ﷺ) said: ‘When anyone of you performs prayer, let him pray facing towards a Sutrah, and let him get close to it, and not let anyone pass in front of him. If someone comes and wants to pass in front of him, let him fight him, for he is a Shaitan (satan).’”

“When anyone of you is performing prayer, he should not let anyone pass in front of him. If he insists then let him fight him, for he has a Qarin (devil-companion) with him.”

“The Prophet (ﷺ) used to pray at night, and I was laying between him and the prayer direction, as a (body for a) funeral horizontally.’”

It was narrated from Zainab bint Umm Salamah that her mother said that her bed was in front of the place where the Messenger of Allah (ﷺ) prostrated.

“The Prophet (ﷺ) used to perform prayer when I was opposite to him, and his garment would sometimes touch me when he prostrated.”

“The Messenger of Allah (ﷺ) forbade performing prayer behind one who is engaged in conversation or one who is sleeping.”

“The Prophet (ﷺ) used to teach us not to bow or prostrate before the Imam; when he says the Takbir then say the Takbir, and when he prostrates, you should prostrate.”

“The Messenger of Allah (ﷺ) said: ‘Does not the one who raises his head before the Imam fear that Allah may turn his head into the head of a donkey?’”

“The Messenger of Allah (ﷺ) said: ‘I have gained weight, so when I bow, then bow, and when I stand up, then stand up, and when I prostrate, then prostrate. I should never find anyone preceding me in bowing or prostration.’”
