Hadith 10:948
Abu Bakr narrated to us, he said: Waki’ narrated to us, from Isra’il, from Abu Ishaq, from Abu al-Ahwas, from ‘Abdullah, who said: He should not divorce her while she is pregnant, for Allah will make him regret it, so he will have to spend on her during her pregnancy and her nursing until she weans him.
حدثنا أبو بكر قال نا وكيع عن إسرائيل عن أبي إسحاق عن أبي الاحوص عن عبد الله قال لا يطلقها وهي حامل فيندمه الله فينفق عليها في حملها ورضاعها حتى تفطمه
