اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ شَرِّ سَمْعِي وَمِنْ شَرِّ بَصَرِي وَمِنْ شَرِّ لِسَانِي وَمِنْ شَرِّ قَلْبِي وَمِنْ شَرِّ مَنِيِّي
O Allaah, I seek refuge in you from the evil of what I hear, from the evil of what I see, from the evil of what I speak, from the evil of what I think, and from the evil of my sperm.
Ref: Sunan Abi Dawud (no. 1551)
