It is narrated from Sayyiduna Shakl bin Humaid (may Allah be pleased with him), he said: I submitted, "O Messenger of Allah! Teach me a supplication from which I may benefit." The Prophet (peace and blessings be upon him) said: «اللَّهُمَّ عَافِنِي مِنْ شَرِّ سَمْعِي، وَبَصَرِي، وَلِسَانِي، وَقَلْبِي، وَشَرِّ مَنِيِّي» "You should supplicate: O Allah! Grant me safety from the evil of my ears, my eyes, my tongue, and my heart. And protect me from the evil of my semen." Waki’ (may Allah have mercy on him) said: "From the evil of semen" means adultery and immorality, that is, I seek Your protection from falling into adultery.
