حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا سُفْيَانُ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ لَوْ غَضَّ النَّاسُ إِلَى الرُّبْعِ، لأَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ الثُّلُثُ، وَالثُّلُثُ كَثِيرٌ أَوْ كَبِيرٌ ‏"‏‏.‏

Narrated Sa`d

I fell sick and the Prophet (ﷺ) paid me a visit. I said to him, "O Allah's Messenger (ﷺ)! I invoke Allah that He may not let me expire in the land whence I migrated (i.e. Mecca)." He said, "May Allah give you health and let the people benefit by you." I said, "I want to will my property, and I have only one daughter and I want to will half of my property (to be given in charity)." He said," Half is too much." I said, "Then I will one third." He said, "One-third, yet even one-third is too much." (The narrator added, "So the people started to will one third of their property and that was Permitted for them.")
