Hadith 10:129
Abu Bakr narrated to us, he said: Hatim ibn Isma'il narrated to us, from Ja'far, from his father, from Ali, who said: If he divorces the virgin once, he has severed her. And if he divorces her three times, she is not lawful for him until she marries a husband other than him.
حدثنا أبو بكر قال نا حاتم بن إسماعيل عن جعفر عن أبيه عن علي قال إذاطلق البكر واحدة فقد بتها وإذا طلقها ثلاثا لم تحل له حتى تنكح زوجا غيره
