Ibn ʿAbbas said, "In the verse: To every one We have appointed ' (Muwaliya Muwaliya means one's) heirs (4.33).' (And regarding the verse) 'And those with whom your right hands have made a pledge.' Ibn ʿAbbas said, "When the emigrants came to the Prophet ﷺ in Medina, the emigrant would inherit the Ansari while the latter's relatives would not inherit him because of the bond of brotherhood which the Prophet established between them (i.e. the emigrants and the Ansar). When the verse: 'And to everyone We have appointed heirs' (4.33) was revealed, it canceled (the bond (the pledge) of brotherhood regarding inheritance)." Then he said, "The verse: To those also to whom your right hands have pledged, remained valid regarding cooperation and mutual advice, while the matter of inheritance was excluded and it became permissible to assign something in one's testament to the person who had the right of inheriting before.  

كَانَ الْمُهَاجِرُونَ لَمَّا قَدِمُوا الْمَدِينَةَ يَرِثُ الْمُهَاجِرُ الأَنْصَارِيَّ دُونَ ذَوِي رَحِمِهِ لِلأُخُوَّةِ الَّتِي آخَى النَّبِيُّ ﷺ بَيْنَهُمْ فَلَمَّا نَزَلَتْ {وَلِكُلٍّ جَعَلْنَا مَوَالِيَ} نَسَخَتْ ثُمَّ قَالَ {وَالَّذِينَ عَقَدَتْ أَيْمَانُكُمْ } إِلاَّ النَّصْرَ وَالرِّفَادَةَ وَالنَّصِيحَةَ وَقَدْ ذَهَبَ الْمِيرَاثُ وَيُوصِي لَهُ  

Regarding the Verse: "To everyone, We have appointed heirs." (4.33) 'Mawali' means heirs. And regarding:-- "And those to whom your right hands have pledged." When the Emigrants came to Medina, an Emigrant used to be the heir of an Ansari with the exclusion of the latter's relatives, and that was because of the bond of brotherhood which the Prophet ﷺ had established between them (i.e. the Emigrants and the Ansar). So when the Verses:-- "To everyone We have appointed heirs." was revealed, (the inheritance through bond of brotherhood) was cancelled. Ibn ʿAbbas then said: "And those to whom your right hands have pledged." is concerned with the covenant of helping and advising each other. So allies are no longer to be the heir of each other, but they can bequeath each other some of their property by means of a will.  

وَرَثَةً {وَالَّذِينَ عَاقَدَتْ أَيْمَانُكُمْ} كَانَ الْمُهَاجِرُونَ لَمَّا قَدِمُوا الْمَدِينَةَ يَرِثُ الْمُهَاجِرُ الأَنْصَارِيَّ دُونَ ذَوِي رَحِمِهِ لِلأُخُوَّةِ الَّتِي آخَى النَّبِيُّ ﷺ بَيْنَهُمْ فَلَمَّا نَزَلَتْ {وَلِكُلٍّ جَعَلْنَا مَوَالِيَ} نُسِخَتْ ثُمَّ قَالَ {وَالَّذِينَ عَاقَدَتْ أَيْمَانُكُمْ } مِنَ النَّصْرِ وَالرِّفَادَةِ وَالنَّصِيحَةِ وَقَدْ ذَهَبَ الْمِيرَاثُ وَيُوصِي لَهُ سَمِعَ أَبُو أُسَامَةَ إِدْرِيسَ وَسَمِعَ إِدْرِيسُ طَلْحَةَ  

"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.
