Muwatta Malik, Book 29, Hadith 1199 (In-Book)

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.

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