Hadith.184 - Al-Halabi said: ‘Imam Jafar ibn Muhammad Al-Sadiq {a.s} was asked about a man who engages in sexual relations with a woman but does not ejaculate. Is ghusl (ritual bathing) required for him? Imam {a.s} said: 'Imam Ali {a.s} used to say, "If the circumcised part touches the circumcised part, ghusl becomes obligatory."'
