Surah Ash-Shu'ara 26:71

قَالُوا۟ نَعْبُدُ أَصْنَامًا فَنَظَلُّ لَهَا عَـٰكِفِينَ

They said, "We worship idols and remain to them devoted."

Translation: Saheeh International

Tafsir

They said ‘We worship idols — they reiterate the verb in the response in order to supplement it with the following remark — and remain cleaving to them’ we remain worshipping them all day; they give a longer response to indicate their misplaced pride in such an act.
