(18) باب الْوَصَاةِ بِكِتَابِ اللَّهِ عَزَّ وَجَلَّ
Narrated Talha:
I asked `Abdullah bin Abi `Aufa, "Did the Prophet (ﷺ) make a will (to appoint his successor or bequeath wealth)?" He replied, "No." I said, "How is it prescribed then for the people to make wills, and they are ordered to do so while the Prophet (ﷺ) did not make any will?" He said, "He made a will wherein he recommended Allah's Book."
