Busr bin Sa'id said that Zaid bin Khalid sent him to Sayyiduna Abu Juhaim Abdullah Ansari (may Allah be pleased with him) to ask him what he had heard from the Prophet Muhammad (peace be upon him) regarding someone passing in front of a person who is praying. Sayyiduna Abu Juhaim (may Allah be pleased with him) said that the Messenger of Allah (peace be upon him) said: If the one passing in front of a person who is praying knew how great a sin it is, he would prefer to stand there for forty rather than pass in front of him.
