حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ دَاوُدَ بْنِ أَبِي هِنْدٍ، عَنْ الشَّعْبِيِّ: "فِي رَجُلٍ كَانَ لَهُ ثَلَاثَةُ بَنِينَ، فَأَوْصَى لِرَجُلٍ مِثْلَ نَصِيبِ أَحَدِهِمْ لَوْ كَانُوا أَرْبَعَةً، قَالَ الشَّعْبِيُّ: يُعْطَى الْخُمُسَ".
It is narrated from Imam Sha'bi, may Allah have mercy on him: If a man has three sons and he makes a bequest for someone equal to the share of one of them, as if he had four sons, Sha'bi, may Allah have mercy on him, said: He will be given one-fifth.
