Strengthening the Ummah

Ibn `Abbas 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 `Abbas 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.
