﴿ يَسْتَفْتُونَكَ قُلِ ٱللَّهُ يُفْتِيكُمْ فِى ٱلْكَلَٰلَةِ ۚ إِنِ ٱمْرُؤٌا۟ هَلَكَ لَيْسَ لَهُۥ وَلَدٌۭ وَلَهُۥٓ أُخْتٌۭ فَلَهَا نِصْفُ مَا تَرَكَ ۚ وَهُوَ يَرِثُهَآ إِن لَّمْ يَكُن لَّهَا وَلَدٌۭ ۚ فَإِن كَانَتَا ٱثْنَتَيْنِ فَلَهُمَا ٱلثُّلُثَانِ مِمَّا تَرَكَ ۚ وَإِن كَانُوٓا۟ إِخْوَةًۭ رِّجَالًۭا وَنِسَآءًۭ فَلِلذَّكَرِ مِثْلُ حَظِّ ٱلْأُنثَيَيْنِ ۗ يُبَيِّنُ ٱللَّهُ لَكُمْ أَن تَضِلُّوا۟ ۗ وَٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌۢ ﴾

“THEY WILL ASK thee to enlighten them. Say: "God enlightens you [thus] about the laws concerning [inheritance from] those who leave no heir in the direct line: If a man dies childless and has a sister, she shall inherit one-half of what he has left, just as he shall inherit from her if she dies childless. But if there are two sisters, both [together] shall have two-thirds of what he has left; and if there are brothers and sisters, then the male shall have the equal of two females' share." God makes [all this] clear unto you, lest you go astray; and God knows everything.”

Giving the injunction regarding inheritance the Quran states, ‘God makes things clear to you so that you will not go astray.’ This shows that inheritance is not a simple matter. This is one of those areas in which disobeying the divine injunction will lead you astray from the straight and narrow path of guidance.
