Chapter 1: Introduction
Al-Faḍl bin Sahl narrated to me, he said, I asked Mu’allā ar-Rāzī about Muhammad bin Sa’īd whom Abbād transmitted from, so he informed me about what Īsā bin Yūnus said: ‘I was at his door and Sufyān was with [Muhammad bin Sa’īd], then when he came out I asked [Sufyān] about him. So he informed me that he was a liar.’
