4:12
وَلَكُمْ نِصْفُ مَا تَرَكَ أَزْوَاجُكُمْ إِنْ لَمْ يَكُنْ لَهُنَّ وَلَد ٌ فَإِنْ كَانَ لَهُنَّ وَلَد ٌ فَلَكُمُ الرُّبُعُ مِمَّا تَرَكْنَ مِنْ بَعْدِ وَصِيَّة ٍ يُوصِينَ بِهَا أَوْ دَيْن ٍ وَلَهُنَّ الرُّبُعُ مِمَّا تَرَكْتُمْ إِنْ لَمْ يَكُنْ لَكُمْ وَلَد ٌ فَإِنْ كَانَ لَكُمْ وَلَد ٌ فَلَهُنَّ الثُّمُنُ مِمَّا تَرَكْتُمْ مِنْ بَعْدِ وَصِيَّة ٍ تُوصُونَ بِهَا أَوْ دَيْن ٍ وَإِنْ كَانَ رَجُل ٌ يُورَثُ كَلاَلَةً أَوْ امْرَأَة ٌ وَلَهُ~ُ أَخٌ أَوْ أُخْت ٌ فَلِكُلِّ وَاحِد ٍ مِنْهُمَا السُّدُسُ فَإِنْ كَانُوا أَكْثَرَ مِنْ ذَلِكَ فَهُمْ شُرَكَاءُ فِي الثُّلُثِ مِنْ بَعْدِ وَصِيَّة ٍ يُوصَى بِهَا أَوْ دَيْنٍ غَيْرَ مُضَارّ ٍ وَصِيَّة ً مِنَ اللَّهِ وَاللَّهُ عَلِيمٌ حَلِيم ٌ

And for you is half of what your wives leave behind if they have no child; but if they have a child then to you is one quarter of what they leave behind. All after a will is carried through or a debt. And to them is one quarter of what you leave behind if you have no child; but if you have a child then to them is one eighth of what you leave behind. All after a will is carried through or a debt. And if a man or a woman who is inheriting has no descendants, but has a brother or a sister, then to each one of them is one sixth, but if they are more than this then they are to share in one third. All after a will is carried through or a debt, which does not cause harm. A directive from God, and God is Knowledgeable, Compassionate.
