167 — Umar ibn Ayyūb related to us, saying: Al-Hasan ibn al-Sabbāh related to us, saying: Ibrāhīm ibn Ziyād related to us, saying: I asked Abd al-Rahmān ibn Mahdī, “What do you say of one who says, ‘The Quran is created’?” He replied, “If I held authority, I would take my stand on the bridge, and no man would pass me without my questioning him. If he said, ‘The Quran is created,’ I would strike off his head and cast him into the water.”
