وَعَنْ اِبْنِ مَسْعُودٍ - رضى الله عنه - فِي بِنْتٍ , وَبِنْتِ اِبْنٍ , وَأُخْتٍ - { قَضَى اَلنَّبِيُّ - صلى الله عليه وسلم -" لِلِابْنَةِ اَلنِّصْفَ , وَلِابْنَةِ اَلِابْنِ اَلسُّدُسَ - تَكْمِلَةَ اَلثُّلُثَيْنِ- وَمَا بَقِيَ فَلِلْأُخْتِ } رَوَاهُ اَلْبُخَارِيُّ 1
Narrated Ibn Mas'ud (RA) concerning the situation where there was a daughter, a son's daughter and a sister: The Prophet (ﷺ) ruled, "The daughter gets half and the son's daughter gets a sixth, completing two-thirds, and what remains goes to the sister." [Reported by al-Bukhari].
