﴿ وَتَٱللَّهِ لَأَكِيدَنَّ أَصْنَٰمَكُم بَعْدَ أَن تُوَلُّوا۟ مُدْبِرِينَ ﴾

“And [he added to himself.] “By God, I shall most certainly bring about the downfall of your idols as soon as you have turned your backs and gone away!””

(And, by Allah) he said this to himself, (I shall circumvent) I shall demolish (your idols after ye have gone away and turned your backs) to go to the festival.
