اَلنَّبِیُّ اَوْلٰى بِالْمُؤْمِنِیْنَ مِنْ اَنْفُسِهِمْ وَ اَزْوَاجُهٗۤ اُمَّهٰتُهُمْ وَ اُولُوا الْاَرْحَامِ بَعْضُهُمْ اَوْلٰى بِبَعْضٍ فِیْ كِتٰبِ اللّٰهِ مِنَ الْمُؤْمِنِیْنَ وَ الْمُهٰجِرِیْنَ اِلَّاۤ اَنْ تَفْعَلُوْۤا اِلٰۤى اَوْلِیٰٓئِكُمْ مَّعْرُوْفًا كَانَ ذٰلِكَ فِی الْكِتٰبِ مَسْطُوْرًا(۶)(سورۃ الاحزاب)
Translation
The Prophet is closer to the believers than their own selves, and his wives are their mothers. And blood-relations are closer to one another in the Book of Allah than the (other) believers and the emigrants, except that you do some good to your friends (by making a will). This has been written in the Book. (6) (Asan Tarjuma-e-Quran)
Meaning: Here Allah Almighty has stated this reality that although the Holy Prophet ﷺ is dearer to all Muslims than their own lives, and all Muslims consider his pure wives as their mothers, yet due to this, the Holy Prophet ﷺ and his pure wives do not get priority over a Muslim's own relatives in the matter of inheritance. Therefore, when someone passes away, his inheritance is distributed among his close relatives; no share is given to the Holy Prophet ﷺ or his pure wives from it, even though from a religious perspective, he and his pure wives hold a greater right than other relatives. When the Holy Prophet ﷺ and his pure wives were not included in the inheritance despite their religious relationship, how can an adopted son be included in the inheritance merely by calling him a son with the tongue? However, if there is an intention to do good to them, a will can be made for them up to the limit of one-third of the estate. (Asan Tarjuma-e-Quran)
