أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ قَالَ حَدَّثَنَا سُفْيَانُ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ ابْنِ عَبَّاسٍ قَالَ لَوْ غَضَّ النَّاسُ إِلَی الرُّبُعِ لِأَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الثُّلُثَ وَالثُّلُثُ کَثِيرٌ أَوْ کَبِيرٌ
سنن نسائی · Hadith 3669
It was narrated that Ibn ‘Abbas said: “If the people were to reduce (their bequests) to one- quarter (of their wealth, that would be better), because the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘One-third, and one-third is much or large.” (Sahih)
