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 (s) passed away. He became one of the Vaqafites and confiscated whatever he had that belonged to Musa ibn Ja’far (s).
