Shakal bin Humaid said:
"I came to the Prophet (ﷺ) and said: 'O Messenger of Allah (ﷺ), teach me a way of seeking refuge so that I may seek refuge by it." He said: "So he (ﷺ) took my hand and said: 'Say:
اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ شَرِّ سَمْعِي وَمِنْ شَرِّ بَصَرِي وَمِنْ شَرِّ لِسَانِي وَمِنْ شَرِّ قَلْبِي وَمِنْ شَرِّ مَنِيِّي
O Allah, indeed I seek refuge in You from
1) The evil of my hearing and
2) The evil of my sight, and
3) The evil of my tongue and
4) The evil of my heart, and
5) The evil of my semen.
