Busr bin Saeed reported that Zaid bin Khalid Juhani sent him to Sayyiduna Abu Juhaim (Abdullah) Ansari, may Allah be pleased with him, to ask him what he had heard from the Messenger of Allah, peace and blessings be upon him, regarding the one who passes in front of a person performing prayer. Sayyiduna Abu Juhaim, may Allah be pleased with him, said: The Messenger of Allah, peace and blessings be upon him, said: "If the one passing in front of the praying person knew how great a sin it is upon him, he would prefer to stand there for forty rather than pass in front of him." Abu Nadr said: I do not remember whether Busr bin Saeed said forty days, or a month, or a year.
