It is narrated from Sayyiduna Shakl (may Allah be pleased with him), he says: I said, O Messenger of Allah! Teach me a supplication from which I may benefit. The Prophet (peace and blessings be upon him) said: Say: "Allahumma inni a'udhu bika min sharri sam'i wa basari wa qalbi wa maniyyi." (O Allah! I seek refuge in You from the evil of my hearing, my sight, my heart, and my semen.)
