Hadith 10:1421
Abu Bakr narrated to us, he said: Hushaym narrated to us, from Mughira, from Ibrahim, who said: He used to say: If his share is fulfilled through his breastfeeding, then it is from his share. And if it is not fulfilled, then it is from the entire wealth.
حدثنا أبو بكر قال نا هشيم عن مغيرة عن إبراهيم قال كان يقول إن وفى رضاعه نصيبه فهو من نصيبه وإن لم يف فهو من جميع المال
