1. We were told by Muhammed bin Ahmad al-Shaybani, may Allah be pleased with him, that he said: We were told by Muhammed bin Abi Abdillah al-Kufi, that he said: We were told by Musa bin Imran al-Nakha’I, from his paternal uncle, Hussain bin Yazid al-Nawfili, from Hasan bin Ali bin Abi Hamza, from his father, from Abu Baseer, that he said: I asked Abu Abdillah, peace be upon him, about the saying of Allah, Exalted and Glorious is He: «And He made it a word that remains in his descendants.» (43:28) He said: It is Imamate; Allah, Exalted and Glorious is He, made it remaining in the descendants of Hussain, peace be upon him, until the Day of Resurrection.
