English Translation
Regarding passing in front of a praying person: Abu Juhaym narrated that the Prophet (peace be upon him) said: "If the one who passes in front of a praying person knew what is upon him, it would be better for him to stand for forty than to pass in front of him." Abu al-Nadr said: "I do not know whether he said forty days, months, or years."
