Chapter on Temporary Marriage (Mutʿah)

Salih ibn Uqbah reported from his father, who reported from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام: I asked him, "Is there a reward for Mut'ah?" He عليه السلام replied: "If he seeks by it the pleasure of Allah سبحانه وتعالى Almighty and to oppose those who deny it, then Allah سبحانه وتعالى writes a good deed for him for every word he speaks to her. When he extends his hand toward her, Allah سبحانه وتعالى writes a good deed for him. When he approaches her, Allah سبحانه وتعالى forgives a sin for him. And when he performs ghusl (ritual purification), Allah سبحانه وتعالى forgives him a number of sins equal to the drops of water that pass over his hair." I asked: "Equal to the number of hairs?" He عليه السلام replied: "Yes, equal to the number of hairs."
