21:65

ثُمَّ نُكِسُوا عَلَىٰ رُءُوسِهِمْ لَقَدْ عَلِمْتَ مَا هَٰؤُلَاءِ يَنطِقُونَ

Transliteration:

Thumma nukisoo AAala ruoosihim laqad AAalimta ma haola-i yantiqoona

Word by Word:

Then they were turned on their heads, "Verily, you know not these (can) speak!"

Translations:

But then they relapsed into their former way of thinking and said: Thou knowest very well that these [idols] cannot speak!"

Then were they confounded with shame: (they said), "Thou knowest full well that these (idols) do not speak!"

And they were utterly confounded, and they said: Well thou knowest that these speak not.

Then they were made to hang down their heads: Thou knowest indeed that they speak not.

Then they reversed themselves, [saying], "You have already known that these do not speak!"
