Surah An-Nisa · Ayah 176

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 request from you a [legal] ruling. Say, "Allah gives you a ruling concerning one having neither descendants nor ascendants [as heirs]." If a man dies, leaving no child but [only] a sister, she will have half of what he left. And he inherits from her if she [dies and] has no child. But if there are two sisters [or more], they will have two-thirds of what he left. If there are both brothers and sisters, the male will have the share of two females. Allah makes clear to you [His law], lest you go astray. And Allah is Knowing of all things.
