Muwatta Malik:Divorce:Hadith 1307
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّهُ كَانَ يَقُولُ فِي الْمَرْأَةِ الْبَدَوِيَّةِ يُتَوَفَّى عَنْهَا زَوْجُهَا إِنَّهَا تَنْتَوِي حَيْثُ انْتَوَى أَهْلُهَا ‏.‏ قَالَ مَالِكٌ وَهَذَا الأَمْرُ عِنْدَنَا ‏.‏

Yahya related to me from Malik that Hisham ibn Urwa said about a Bedouin woman whose husband died, that she was to stay where her people stayed.

Malik said, “This is what is done among us.”
