وَإِذَا قِيلَ لَهُمُ ٱسۡجُدُواْۤ لِلرَّحۡمَٰنِ قَالُواْ وَمَا ٱلرَّحۡمَٰنُ أَنَسۡجُدُ لِمَا تَأۡمُرُنَا وَزَادَهُمۡ نُفُورٗا۩ ٦٠
And when it is said to them, "Prostrate to the Most Merciful," they say, "And what is the Most Merciful? Should we prostrate to that which you order us?" And it increases them in aversion.
Translation: Saheeh International (English)
Each word's meaning and sound
When it is said to the disbelievers: Prostrate to the Merciful, they say: We will not prostrate to the Merciful. What is the Merciful? We do not know or acknowledge Him. Should we prostrate to what you tell us when we do not know Him?! His instruction to them to prostrate to Him only puts them further away from having faith in Allah.
