"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 جَاءَهُ وَهُوَ مَرِيضٌ فَقَالَ إِنَّهُ لَيْسَ لِي وَلَدٌ إِلَّا ابْنَةٌ وَاحِدَةٌ فَأُوصِي بِمَالِي كُلِّهِ؟ قَالَ النَّبِيُّ ﷺ «لَا» قَالَ فَأُوصِي بِنِصْفِهِ؟ قَالَ النَّبِيُّ ﷺ «لَا» قَالَ فَأُوصِي بِثُلُثِهِ؟ قَالَ «الثُّلُثُ وَالثُّلُثُ كَبِيرٌ»
