To will one-third of one's property
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 Ibn `Abbas: I recommend that people reduce the proportion of what they bequeath by will to the fourth (of the whole legacy), for Allah's Messenger (ﷺ) said, "One-third, yet even one third is too much."
