Celibacy

CELIBACY (Arabic `Uzubah), although not absolutely condemned by Muhammad, is held to be a lower form of life to that of marriage. It is related that `Usman ibn Maz`un wished to lead a celebate life and the Prophet forbade him, for, said he, “When a Muslim marries he perfects his religion.” (Mishkat, book xii., c. xx.)
