5- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ عَنِ الْعَلاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ قَالَ أَبُو جَعْفَرٍ الْوَصِيَّةُ حَقٌّ وَقَدْ أَوْصَى رَسُولُ اللهِ ﷺ فَيَنْبَغِي لِلْمُسْلِمِ أَنْ يُوصِيَ.
5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad, from ibn Mahbub from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has narrated the following: “Abu Ja‘far , has said, ‘Making a will is a right that requires compliance. The Messenger of Allah , made a will, thus it is proper for a Muslim to make a will.’”
