4-25 In another tradition from (The author of the book narrated) my father - may God be pleased with him - it is narrated that Sa’d ibn Abdullah quoted on the authority of Muhammad ibn Isa ibn Obayd, on the authority Ziyad ibn Marwan al-Qandi, “I went to see Abi Ibrahim صلى الله عليه وعلى آله وسلم. His son Ali was with him. He told me, ‘O Ziyad! This is his writing that is (just as effective as) my writing. His words are my words. His messenger is my messenger. And whatever he says, (the truth) is in what he says.’”The author of this book (Sheikh Sadooq) said, “In fact, Ziyad ibn Marwan al-Qandi narrated this tradition. But he later denied it after Musa صلى الله عليه وعلى آله وسلم passed away. He became one of the Vaqafites and confiscated whatever he had that belonged to Musa ibn Ja’far صلى الله عليه وعلى آله وسلم.
