Muhammad b. al-Hasan b. Ahmad b. al-Walid narrated to us. He said: Muhammad b. al-Hasan al-Saffar narrated to us from al-`Abbas b. Ma`ruf from `Ali b. Mahzayar. He said: I wrote to Abi Ja`far Muhammad b. `Ali b. Musa al-Rida : May I be your sacrifice! I pray behind one who claims the doctrine of the body and takes the doctrine of Yunus b. `Abd al-Rahman. So, he wrote:

Do not pray behind them, and do not give them zakat. I dissociate from them, and Allah dissociates from them.
