Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi) - كتاب المغازى
حدثنا أبو نعيم، حدثنا مالك بن مغول، عن طلحة، قال سألت عبد الله بن أبي أوفى رضى الله عنهما أوصى النبي صلى الله عليه وسلم فقال لا. فقلت كيف كتب على الناس الوصية أو أمروا بها قال أوصى بكتاب الله.
Narrated Talha: I asked `Abdullah bin Abu `Aufa "Did the Prophet make a will? ' He replied, "No." I further asked, "How comes it that the making of a will was enjoined on the people or that they were ordered to make it? " He said, "The Prophet made a will concerning Allah's Book."
