"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.
فِي قَوْلِهِ { وَالَّذِينَ عَقَدَتْ أَيْمَانُكُمْ فَآتُوهُمْ نَصِيبَهُمْ } قَالَ كَانَ الْمُهَاجِرُونَ حِينَ قَدِمُوا الْمَدِينَةَ تُوَرِّثُ الأَنْصَارَ دُونَ ذَوِي رَحِمِهِ لِلأُخُوَّةِ الَّتِي آخَى رَسُولُ اللَّهِ ﷺ 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
