1. We were told by Ali bin Ahmad bin Abdullah bin Ahmad bin Abi Abdillah al-Barqi, that he said: I was told by my father, from his grandfather, Ahmad bin Abi Abdillah, from his father, Muhammed bin Khalid, from Yunus bin Abdul-Rahman, that he said: I asked Musa bin Ja’far, peace be upon them both, about the saying of Allah, Exalted and Glorious is He: «Indeed, Allah orders you to deliver the trusts to their people» (4:58). So he said: This is addressing us, in particular. Allah, Blessed and Exalted is He, ordered every Imam from us to deliver to the Imam who is after him and to bequeath to him. It is then, furthermore, continuous in the rest of the trusts. I was, verily, told by my father, of his father, that Ali bin Hussain, peace be upon them both, said to his companions: You must deliver the trusts, for if the killer of my father, Hussain bin Ali, peace be upon them both, had entrusted me with the sword by which he killed him, I would, verily, have delivered it to him.
