يَسْتَفْتُونَكَ قُلِ ٱللَّهُ يُفْتِيكُمْ فِى ٱلْكَلَـٰلَةِ ۚ إِنِ ٱمْرُؤٌا۟ هَلَكَ لَيْسَ لَهُۥ وَلَدٌ وَلَهُۥٓ أُخْتٌ فَلَهَا نِصْفُ مَا تَرَكَ ۚ وَهُوَ يَرِثُهَآ إِن لَّمْ يَكُن لَّهَا وَلَدٌ ۚ فَإِن كَانَتَا ٱثْنَتَيْنِ فَلَهُمَا ٱلثُّلُثَانِ مِمَّا تَرَكَ ۚ وَإِن كَانُوٓا۟ إِخْوَةً رِّجَالًا وَنِسَآءً فَلِلذَّكَرِ مِثْلُ حَظِّ ٱلْأُنثَيَيْنِ ۗ يُبَيِّنُ ٱللَّهُ لَكُمْ أَن تَضِلُّوا۟ ۗ وَٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌۢ
They request from you a [legal] ruling. Say, "Allāh 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. Allāh makes clear to you [His law], lest you go astray. And Allāh is Knowing of all things.

Narrated Al-Bara:"A man came to the Messenger of Allah (ﷺ) and said: 'O Messenger of Allah! They ask you about a legal verdict. Say: "Allah directs (thus) regarding Al-Kalalah (4:176)." So the Prophet (ﷺ) said to him: "You should be sufficed with the Ayah of summer." (Meaning this Ayah, while in An-Nisa number 12, is mention of the topic, and it was revealed in the winter, this Ayah, revealed in the summer - the last revealed about it - explains it)
