"I do not have any children apart from one daughter. Shall I bequeath all my wealth?" The Prophet said: "No." He said: "Shall I bequeath half of it?" The Prophet said: "No." He said: "Shall I bequeath one-third of it?" He said: "One-third, and one-third is much or large." (Using translation from Nasāʾī 3635)
أَنَّ النَّبِيَّ ﷺ دَخَلَ عَلَيْهِ بِمَكَّةَ وَهُوَ مَرِيضٌ فَقَالَ إِنَّهُ لَيْسَ لِي إِلا ابْنَةٌ وَاحِدَةٌ أفَأُوصِِي بِمَالِي كُلِّهِ؟ فَقَالَ النَّبِيُّ ﷺ لَا قَالَ فَأُوصِي بِنِصْفِهِ؟ قَالَ النَّبِيُّ ﷺ لَا قَالَ فَأُوصِي بِثُلُثِهِ؟ قَالَ الثُّلُثُ وَالثُّلُثُ كَبِيرٌ
