 ٤ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ بُكَيْرٍ وَجَمِيلٍ عَنْ عَمْرِو بْنِ مُصْعَبٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلام) يَقُولُ أَ تَرَوْنَ أَنَّ الْمُوصِيَ مِنَّا يُوصِي إِلَى مَنْ يُرِيدُ لا وَالله وَلَكِنَّهُ عَهْدٌ مِنْ رَسُولِ الله (صَلَّى اللهُ عَلَيْهِ وَآلِه) إِلَى رَجُلٍ فَرَجُلٍ حَتَّى انْتَهَى إِلَى نَفْسِهِ.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibn Abi ‘Umayr from ibn Bukayr and Jamil from ‘Amr ibn Mu‘ab who has said that I heard abu ‘Abdallah  say the following. “Do you think that a testator of us chooses whoever he wants as the executor of his will? No, I swear by Allah, it is not so. It is a covenant from the Messenger of Allah to a man and then to next man. Until the Imam (abu ‘Abdallah  ended up to his self.” The Imam  six times said, “To the next man.” 1. The case with David and Solomon  is referred to in the Holy Quran (21:78 – 79) .
