1. My father said: Sa`d ibn `Abd Allah said: Ahmad ibn Muhammad ibn `Isa, on the authority of al-Hasan ibn Mahbub, on the authority of `Ali ibn Ra’ab, on the authority of Abu Basir that Abu Ja`far al-Baqir said: “Discuss the creation of Allah, but refrain from discussing about Allah. Verily, discussing about Allah causes nothing but confusion.”
