Hadith.4600 - Salih ibn Uqbah reported from his father, who reported from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir : I asked him, "Is there a reward for Mut'ah?" He replied: "If he seeks by it the pleasure of Allah (swt) Almighty and to oppose those who deny it, then Allah (swt) writes a good deed for him for every word he speaks to her. When he extends his hand toward her, Allah (swt) writes a good deed for him. When he approaches her, Allah (swt) forgives a sin for him. And when he performs ghusl (ritual purification), Allah (swt) 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 replied: "Yes, equal to the number of hairs."
