I said to him , meaning Abu al-hasan al-Rida : “May I be your ransom! One of your followers told me to ask you a question about something.” He said: “And who would that be?” I said: “Al-Hasan ibn Sahl.” He asked: “What is the issue about?’ I replied: “It is about Divine Unity.” He said: “What about Divine Unity?” I said: “He wants to know whether Allah possesses a body or not?” He answered me: There are three positions regarding Divine Unity. The first group attempts to describe Him through anthropomorphism. The second group attempts to describe Him through negation.

The correct position is attempting to describe him without falling into anthropomorphism.
