I recommend that people reduce the proportion of what they bequeath by will to the fourth (of the whole legacy), for Messenger of Allah ﷺ said, "One-third, yet even one third is too much."
لَوْ غَضَّ النَّاسُ إِلَى الرُّبْعِ لأَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «الثُّلُثُ، وَالثُّلُثُ كَثِيرٌ۔» أَوْ «كَبِيرٌ۔»
