It was narrated from Musa bin Talhah that his father said: “We used to perform prayer while the beasts were passing in front of us.

Busr bin Sa’eed said: “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."

It was narrated from Busr bin Sa’eed that Zaid bin Khalid sent word to Abu Juhaim Al-Ansari asking him: “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.”

It was narrated that Abu Hurairah said: “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.’”

It was narrated from Ibn ‘Abbas that the Prophet (ﷺ) said: “The prayer is severed by a black dog and a woman who has reached the age of menstruation.”
