Hadith 10:1113
Abu Bakr narrated to us, he said: Abda narrated to us, from Abdullah, from Nafi, from Ibn Umar, who said: The woman who has been irrevocably divorced (al-mubattuta) and the woman whose husband has died shall not spend the night except in her house until her waiting period (iddah) has expired.
حدثنا أبو بكر قال نا عبدة عن عبد الله عن نافع عن بن عمر قال لا تبيت المبتوتة ولا المتوفى عنها زوجها إلا في بيتها حتى تنقضي عدتها
