Surah Al-Ahzab, ayah 6

ٱلنَّبِيُّ أَوۡلَىٰ بِٱلۡمُؤۡمِنِينَ مِنۡ أَنفُسِهِمۡۖ وَأَزۡوَٰجُهُۥٓ أُمَّهَٰتُهُمۡۗ وَأُوْلُواْ ٱلۡأَرۡحَامِ بَعۡضُهُمۡ أَوۡلَىٰ بِبَعۡضٖ فِي كِتَٰبِ ٱللَّهِ مِنَ ٱلۡمُؤۡمِنِينَ وَٱلۡمُهَٰجِرِينَ إِلَّآ أَن تَفۡعَلُوٓاْ إِلَىٰٓ أَوۡلِيَآئِكُم مَّعۡرُوفٗاۚ كَانَ ذَٰلِكَ فِي ٱلۡكِتَٰبِ مَسۡطُورٗا ٦

The Prophet is more worthy of the believers than themselves,¹¹⁸² and his wives are [in the position of] their mothers. And those of [blood] relationship are more entitled [to inheritance] in the decree of Allāh than the [other] believers and the emigrants, except that you may do to your close associates a kindness [through bequest]. That was in the Book¹¹⁸³ inscribed.
