It is narrated from Mujahid (may Allah have mercy on him) concerning the saying of Allah Almighty: "or male attendants who have no desire" [Surah al-Nur: 31], that it refers to one who is concerned with nothing but his stomach, and from whom there is no fear for women. Tawus (may Allah have mercy on him) said: It refers to the foolish person who has no need of women. Al-Hasan (may Allah have mercy on him) said: (It is) the one who has no sense, who does not desire women and whom women do not desire.
