But afterwards, (under the influence of the same factors causing them to disbelieve) they relapsed into their former way of believing, and said to Abraham: "You know very well that these (images) cannot speak."
Thereafter they were made to relapse (Literally: they were turned upon their heads) (into idolatry), (saying), "Indeed you already know that these (can) in no way pronounce (a word)."
Confounded as they were, lowering their heads they said, "You know fully well that they cannot speak."

As an effect they were compelled to lower down their heads in humiliation (saying): “Surely, indeed, you (O Ibrahim) knew that these do not talk (either to us or to themselves).”
Then they were turned upside down upon their heads (i.e., their thinking reverted and they said: ‘Ibrahim [Abraham]), surely you yourself know that they do not speak.
