[Machine] Regarding Al-Sha'bi's statement about a man who had three sons and he appointed a man to receive an equal share as one of them if they were four, Al-Sha'bi said, "He shall be given one-fifth."  

الدارمي:٣٢٩٥حَدَّثَنَا 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»
