Sayyiduna Muhammad bin Sirin (may Allah have mercy on him) says: A person said to Sayyiduna Abu Hurairah (may Allah be pleased with him): You have given us fatwas about everything; it seems you will soon start giving us fatwas even about defecation. He said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever relieves himself or commits impurity on a path used by Muslims, upon him is the curse of Allah, the angels, and all people."
