5. Muhammad ibn al-Hasan ibn Ahmad ibn al-Walid said: Muhammad ibn al-Hasan alSaffar, on the authority of Sahl ibn Ziyad, on the authority of Muhammad ibn Isma`il ibn Bazi, on the authority of Muhammad ibn Zayd that I came to (`Ali) al-Rida asking him about Divine Unity, so he dictated to me: All praise be to Allah, the Originator, Producer, and Innovator [Mubtadi`] of all things from the beginning by His Power and Wisdom, not from anything that could invalidate His Invention, nor for nay wrong cause. He created whatever He wanted how He wanted, and He did so independently in order to manifest His Wisdom, and the Reality of His Lordship. Intellects cannot grasp Him. Imagination cannot reach Him. Eyes cannot perceive Him, and scale cannot encompass Him. Speech is incapable without Him. Eyes are expressionless without Him, and rhetoric of description goes astray in Him. He is hidden without a veil and is covered without a covering. He is recognized without seeing. He is described without an image. And He is praised despite the face that He does not possess a body. There is no god but Allah, the great, the Most Exalted.”
