It was narrated from Shutair bin Shakal bin Humaid, that his father said: “I said: ‘Messenger of Allah صلی اللہ علیہ وآلہ وسلم, teach me a supplication from which I may benefit.’ He said:
‘Say:(Allah, protect me from the evil of my hearing, my seeing, my tongue and my heart, and the evil of my sperm.)” — Meaning his sexual organ. (Hasan)
