12. Muhammad ibn al-Hasan ibn Ahmad ibn al-Walid said: Muhammad ibn al-Hasan alSaffar said, on the authority of Muhammad ibn `Isa ibn `Ubayd, on the authority of al-Hasan ibn Mahbub, on the authority of `Ali ibn Ri’ab, on the authority of more than one person that Abu `Abd Allah al-Sadiq said: Whoever serves Allah with his imagination, disbelieves (in Allah). Whoever serves His name without (understanding) the meaning, disbelieves in Allah. Whoever serves both His name and its meaning, has given a partner to Allah. Whoever serves Allah by means of the meanings of the Names of Allah has attributed Himself with, has faith in Allah, which his tongue utters in private and in public. Such are the followers of the Commander of the Faithful. In another version, the last sentence of the tradition is: “These are the true Believes.”
