حَدَّثَنَا هَارُونُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا أَبُو أُسَامَةَ، حَدَّثَنِي إِدْرِيسُ بْنُ يَزِيدَ، حَدَّثَنَا طَلْحَةُ بْنُ مُصَرِّفٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، فِي قَوْلِهِ ‏{‏ وَالَّذِينَ عَقَدَتْ أَيْمَانُكُمْ فَآتُوهُمْ نَصِيبَهُمْ ‏}‏ قَالَ كَانَ الْمُهَاجِرُونَ حِينَ قَدِمُوا الْمَدِينَةَ تُوَرِّثُ الأَنْصَارَ دُونَ ذَوِي رَحِمِهِ لِلأُخُوَّةِ الَّتِي آخَى رَسُولُ اللَّهِ صلى الله عليه وسلم بَيْنَهُمْ فَلَمَّا نَزَلَتْ هَذِهِ الآيَةُ ‏{‏ وَلِكُلٍّ جَعَلْنَا مَوَالِيَ مِمَّا تَرَكَ ‏}‏ قَالَ نَسَخَتْهَا ‏{‏ وَالَّذِينَ عَقَدَتْ أَيْمَانُكُمْ فَآتُوهُمْ نَصِيبَهُمْ ‏}‏ مِنَ النُّصْرَةِ وَالنَّصِيحَةِ وَالرِّفَادَةِ وَيُوصِي لَهُ وَقَدْ ذَهَبَ الْمِيرَاثُ ‏.‏

Ibn 'Abbas explained the following Qur'anic verse :"To those also, to whom your right hand was pledged, give your portion." When the Emigrants came to Medina. they inherited from the Helpers without any blood-relationship with them for the brotherhood which the Messenger of Allah (ﷺ) established between them. When the following verse was revealed: "To (benefit) everyone we have appointed shares and heirs to property left by parent and relatives." it abrogated the verse: "To those also, to whom your right hand was pledged, give their due portion." This alliance was made for help, well wishing and cooperation. Now a legacy can be made for him. (The right to)inheritance was abolished
