Book 29, Hadith 90
Arabic hadith text
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ كَانَ يَقُولُ لاَ تَبِيتُ الْمُتَوَفَّى عَنْهَا زَوْجُهَا وَلاَ الْمَبْتُوتَةُ إِلاَّ فِي بَيْتِهَا .
Translation
Yahya related to me from Malik from Nafi that Abdullan ibn Umarsaid, "The only place a woman whose husband has died and a woman whois absolutely divorced can spend the night is in their houses."
