"And to everyone, We have appointed heirs of that (property) left by parents and relatives. To those, also, with whom you have made a pledge (brotherhood), give them their due portion [by Wasiya (wills)]. Truly, Allah is Ever a Witness over all things." (V.4:33)
Authentic
hadith of Sahih al-Bukhari
Sahih al-Bukhari 4580
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 `Abbas 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.

كَانَ الْمُهَاجِرُونَ حِينَ قَدِمُوا الْمَدِينَةَ يَرِثُ الأَنْصَارِيُّ الْمُهَاجِرِيَّ دُونَ ذَوِي رَحِمِهِ لِلأُخُوَّةِ الَّتِي آخَى النَّبِيُّ صلى الله عليه وسلم بَيْنَهُمْ
