Muwatta Malik 1196

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ الْفَضْلِ، عَنِ الأَعْرَجِ، أَنَّ عُثْمَانَ بْنَ عَفَّانَ، وَرَّثَ نِسَاءَ ابْنِ مُكْمِلٍ مِنْهُ وَكَانَ طَلَّقَهُنَّ وَهُوَ مَرِيضٌ ‏.‏

Yahya related to me from Malik from Abdullah ibn al-Fadl from al- Araj that Uthman ibn Affan made the wives of ibn Mukmil inherit from him, and he had divorced them while he was terminally ill
