حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عُرْوَةَ بْنَ الزُّبَيْرِ، كَانَ يَقُولُ فِي وَلَدِ الْمُلاَعَنَةِ وَوَلَدِ الزِّنَا إِنَّهُ إِذَا مَاتَ وَرِثَتْهُ أُمُّهُ حَقَّهَا فِي كِتَابِ اللَّهِ عَزَّ وَجَلَّ وَإِخْوَتُهُ لأُمِّهِ حُقُوقَهُمْ وَيَرِثُ الْبَقِيَّةَ مَوَالِي أُمِّهِ إِنْ كَانَتْ مَوْلاَةً وَإِنْ كَانَتْ عَرَبِيَّةً وَرِثَتْ حَقَّهَا وَوَرِثَ إِخْوَتُهُ لأُمِّهِ حُقُوقَهُمْ وَكَانَ مَا بَقِيَ لِلْمُسْلِمِينَ ‏.‏ قَالَ مَالِكٌ وَبَلَغَنِي عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، مِثْلُ ذَلِكَ ‏.‏ قَالَ مَالِكٌ وَعَلَى ذَلِكَ أَدْرَكْتُ أَهْلَ الْعِلْمِ بِبَلَدِنَا ‏.

Yahya related to me from Malik that he had heard that Urwa ibnaz-Zubayr said about the child of lian and the child of fornication,that if they died, the mother inherited her right from them accordingto the Book of Allah, the Mighty, the Majestic! The siblings by themother had their rights. The rest was inherited by the former mastersof the mother if she was a freed slave. If she was a free woman byorigin, she inherited her due and the siblings by the mother inheritedtheir due, and the rest went to the Muslims. Malik said, "Iheard the same as that from Sulayman ibn Yasar." Malik said,"That is what I saw the people of knowledge in our city doing." Translation Not Available
