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!"
