Tell the `Abbasid to refrain fro talking about Divine Unity and similar subjects. He should speak to the people about things they are acquainted with, and refrain from things of which they have no knowledge. If they ask you about Divine Unity, then say as Allah, the Mighty and High, has said: Say: He, Allah, is One. Allah is He on whom all depend. He begets not, nor is He begotten. And none is like Him.1 If they ask you to describe Allah, then say that Allah, the Mighty and High, has said: Nothing is a likeness of Him.2 And if they ask you about Allah’s ability to listen, then say what Allah, the Mighty and High, has said: He is the Hearing, the Knowing.3 Hence, speak to the people with what they are acquainted with.
