الآية رقم (12) - وَلَكُمْ نِصْفُ مَا تَرَكَ أَزْوَاجُكُمْ إِن لَّمْ يَكُن لَّهُنَّ وَلَدٌ فَإِن كَانَ لَهُنَّ وَلَدٌ فَلَكُمُ الرُّبُعُ مِمَّا تَرَكْنَ مِن بَعْدِ وَصِيَّةٍ يُوصِينَ بِهَا أَوْ دَيْنٍ وَلَهُنَّ الرُّبُعُ مِمَّا تَرَكْتُمْ إِن لَّمْ يَكُن لَّكُمْ وَلَدٌ فَإِن كَانَ لَكُمْ وَلَدٌ فَلَهُنَّ الثُّمُنُ مِمَّا تَرَكْتُم مِّن بَعْدِ وَصِيَّةٍ تُوصُونَ بِهَا أَوْ دَيْنٍ وَإِن كَانَ رَجُلٌ يُورَثُ كَلاَلَةً أَو امْرَأَةٌ وَلَهُ أَخٌ أَوْ أُخْتٌ فَلِكُلِّ وَاحِدٍ مِّنْهُمَا السُّدُسُ فَإِن كَانُوَاْ أَكْثَرَ مِن ذَلِكَ فَهُمْ شُرَكَاء فِي الثُّلُثِ مِن بَعْدِ وَصِيَّةٍ يُوصَى بِهَآ أَوْ دَيْنٍ غَيْرَ مُضَآرٍّ وَصِيَّةً مِّنَ اللّهِ وَاللّهُ عَلِيمٌ حَلِيمٌ

(12) - {And for you is half of what your wives leave if they have no child. But if they have a child, for you is one fourth of what they leave, after any bequest they [may have] made or debt. And for the wives is one fourth if you leave no child. But if you leave a child, then for them is an eighth of what you leave, after any bequest you [may have] made or debt. And if a man or woman leaves neither ascendants nor descendants but has a brother or a sister, then for each one of them is a sixth. But if they are more than two, they share a third, after any bequest which was made or debt, as long as there is no detriment [caused]. [This is] an ordinance from Allah, and Allah is Knowing and Forbearing.}

We leave the details of the quarter and the eighth here to the specialists because it relates to the provisions of inheritance.

مِن بَعْدِ وَصِيَّةٍ يُوصِينَ بِهَا أَوْ دَيْنٍ {after any bequest they [may have] made or debt.}: Always after a will or debt, you cannot distribute the inheritance until the rights attached to this inheritance are taken out.

وَإِن كَانَ رَجُلٌ يُورَثُ كَلاَلَةً {And if a man or woman leaves neither ascendants nor descendants}: That is, he has neither a father nor a son.

وَلَهُ أَخٌ أَوْ أُخْتٌ {but has a brother or a sister,}: Brother and sister here from his mother’s side; because the provisions of full brotherhood come in another place.

غَيْرَ مُضَآرٍّ {as long as there is no detriment [caused].}: Distributing the inheritance in this way cannot harm anyone; Because it is a divine distribution and it is an obligation from Allah (swt).
