Surah Al-Anbiya Verse 57 - English Translation by Dr Kamal Omar
Surah Al-Anbiyaوَتَٱللَّهِ لَأَكِيدَنَّ أَصۡنَٰمَكُم بَعۡدَ أَن تُوَلُّواْ مُدۡبِرِينَ
And (I make) Allah as Witness. Surely, I shall plot a plan (for) your idols after when you have returned showing (your) backs (to me)." [This was a vague indication that the incident shall occur in the temple when a congregation is dispersed and people are returning with their backs towards the temple]
