Sayyiduna Abu Hurairah (may Allah be pleased with him) says: I submitted, “O Messenger of Allah! Indeed, I am a young, unmarried man, and I fear the trial of desire for myself. Grant me permission to become castrated.” So the Messenger of Allah (peace and blessings be upon him) said: “Whatever is to befall you, the pen has already written it and it has dried, so whether you become castrated or refrain (it will not change anything).”
