وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ الثِّقَةِ، عِنْدَهُ أَنَّهُ سَمِعَ سَعِيدَ بْنَ الْمُسَيَّبِ، يَقُولُ أَبَى عُمَرُ بْنُ الْخَطَّابِ أَنْ يُوَرِّثَ، أَحَدًا مِنَ الأَعَاجِمِ إِلاَّ أَحَدًا وُلِدَ فِي الْعَرَبِ ‏.‏ قَالَ مَالِكٌ وَإِنْ جَاءَتِ امْرَأَةٌ حَامِلٌ مِنْ أَرْضِ الْعَدُوِّ فَوَضَعَتْهُ فِي أَرْضِ الْعَرَبِ فَهُوَ وَلَدُهَا يَرِثُهَا إِنْ مَاتَتْ وَتَرِثُهُ إِنْ مَاتَ مِيرَاثَهَا فِي كِتَابِ اللَّهِ ‏.‏ قَالَ مَالِكٌ الأَمْرُ الْمُجْتَمَعُ عَلَيْهِ عِنْدَنَا وَالسُّنَّةُ الَّتِي لاَ اخْتِلاَفَ فِيهَا وَالَّذِي أَدْرَكْتُ عَلَيْهِ أَهْلَ الْعِلْمِ بِبَلَدِنَا أَنَّهُ لاَ يَرِثُ الْمُسْلِمُ الْكَافِرَ بِقَرَابَةٍ وَلاَ وَلاَءٍ وَلاَ رَحِمٍ وَلاَ يَحْجُبُ أَحَدًا عَنْ مِيرَاثِهِ ‏.‏ قَالَ مَالِكٌ وَكَذَلِكَ كُلُّ مَنْ لاَ يَرِثُ إِذَا لَمْ يَكُنْ دُونَهُ وَارِثٌ فَإِنَّهُ لاَ يَحْجُبُ أَحَدًا عَنْ مِيرَاثِهِ ‏.‏

Yahya related to me from Malik from a reliable source of his whohad heard Said ibn al-Musayyab say, ''Umar ibn al-Khattab refused tolet anyone inherit from the non-arabs except for one who was bornamong the arabs." Malik said, "If a pregnant woman comes fromthe land of the enemy and gives birth in arab land so that he is her(an arab) child, he inherits from her if she dies, and she inheritsfrom him if he dies, by the Book of Allah." Malik said, "Thegenerally agreed on way of doing things among us and the sunna inwhich there is no dispute, and what I saw the people of knowledge inour city doing, is that a Muslim does not inherit from a kafir bykinship, clientage (wala'), or maternal relationship, nor does he (theMuslim) overshadow any (of the kafirs) from his inheritance. Malik said, "Similarly, someone who forgoes his inheritance when he isthe chief heir does not overshadow anyone from his inheritance." Translation Not Available
