Sahih Bukhari Volume 7, Book 75, Hadith 5661

حَدَّثَنَا الْمَكِّيُّ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا الْجُعَيْدُ، عَنْ عَائِشَةَ بِنْتِ سَعْدٍ، أَنَّ أَبَاهَا، قَالَ تَشَكَّيْتُ بِمَكَّةَ شَكْوًا شَدِيدًا، فَجَاءَنِي النَّبِيُّ صلى الله عليه وسلم يَعُودُنِي، فَقُلْتُ يَا نَبِيَّ اللَّهِ إِنِّي أَتْرُكُ مَالاً وَإِنِّي لَمْ أَتْرُكْ إِلاَّ ابْنَةً وَاحِدَةً، فَأُوصِي بِثُلُثَىْ مَالِي وَأَتْرُكُ الثُّلُثَ فَقَالَ ‏"‏ لاَ ‏"‏‏.‏ قُلْتُ فَأُوصِي بِالنِّصْفِ وَأَتْرُكُ النِّصْفَ قَالَ ‏"‏ لاَ ‏"‏‏.‏ قُلْتُ فَأُوصِي بِالثُّلُثِ وَأَتْرُكُ لَهَا الثُّلُثَيْنِ قَالَ ‏"‏ الثُّلُثُ وَالثُّلُثُ كَثِيرٌ ‏"‏‏.‏ ثُمَّ وَضَعَ يَدَهُ عَلَى جَبْهَتِهِ، ثُمَّ مَسَحَ يَدَهُ عَلَى وَجْهِي وَبَطْنِي ثُمَّ قَالَ ‏"‏ اللَّهُمَّ اشْفِ سَعْدًا وَأَتْمِمْ لَهُ هِجْرَتَهُ ‏"‏‏.‏ فَمَا زِلْتُ أَجِدُ بَرْدَهُ عَلَى كَبِدِي فِيمَا يُخَالُ إِلَىَّ حَتَّى السَّاعَةِ‏

Narrated By Sad : I became seriously ill at Mecca and the Prophet came to visit me. I said, "O Allah's Apostle! I shall leave behind me a good fortune, but my heir is my only daughter; shall I bequeath two third of my property to be spent in charity and leave one third (for my heir)?" He said, "No." I said, "Shall I bequeath half and leave half?" He said, "No." I said, "Shall I bequeath one third and leave two thirds?" He said, "One third is alright, though even one third is too much." Then he placed his hand on his forehead and passed it over my face and abdomen and said, "O Allah! Cure Sad and complete his emigration." I feel as if I have been feeling the coldness of his hand on my liver ever since.
