Hadith 10:204
Abu Bakr narrated to us, he said: Waki’ narrated to us, from Abu al-Mu’tamir, from Qatadah, who said: Insanity is of two types. If he does not regain consciousness, his divorce is not valid for him. And if he regains consciousness and divorces during his state of consciousness, it is binding upon him.
حدثنا أبو بكر قال نا وكيع عن أبي المعتمر عن قتادة قال الجنون جنونان فإن كان لا يفيق لم يجز له طلاق وإن كان يفيق فطلق في حال إفاقته لزمه ذلك
