Musa bin Abdullah, may Allah have mercy on him, who was a truthful man, narrates from a female Companion from Banu Abd Ashhal, may Allah be pleased with her, she says: I said, "O Messenger of Allah! The path we take to the mosque is foul-smelling; what should we do when it rains?" He (peace and blessings be upon him) said: "Is there not a clean path after that?" She said: "Yes, of course." He (peace and blessings be upon him) said: "Then that path is in place of this one." In another narration, he (peace and blessings be upon him) said: "This clean path will remove the effect (of impurity) of that (unclean path)."
