5412 - وَ رَوَى اَلْعَلاَءُ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ قَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ : "اَلْوَصِيَّةُ حَقٌّ وَ قَدْ أَوْصَى رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ فَيَنْبَغِي لِلْمُسْلِمِ أَنْ يُوصِيَ ".
Hadith.5412 - Al-Ala' narrated from Muhammad ibn Muslim, who said that Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) said: "Making a will is a duty, and the Messenger of Allah (swt) (peace be upon him and his family) indeed made a will. Therefore, it is appropriate for a Muslim to make a will."
