I asked 'Abdullah b. Abu Aufa whether Messenger of Allah ﷺ had made any will (in regard to his property). He said: NO. I said: Then why has making of will been made necessary for the Muslims, or why were they commanded to make will? Thereupon he said: He made the will according to the Book of Allah, the Exalted and Majestic.
سَأَلْتُ عَبْدَ اللَّهِ بْنَ أَبِي أَوْفَى هَلْ أَوْصَى رَسُولُ اللَّهِ ﷺ فَقَالَ لاَ قُلْتُ فَلِمَ كُتِبَ عَلَى الْمُسْلِمِينَ الْوَصِيَّةُ أَوْ فَلِمَ أُمِرُوا بِالْوَصِيَّةِ قَالَ أَوْصَى بِكِتَابِ اللَّهِ ﷻ
