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. Al-Furqan 25:60 ⧉
Tafsir:
قَالُوا وَمَا الرَّحْمَـٰنُ (60) The word رَّحْمَـٰنُ (Rahman, translated as All-Merciful) is an Arabic word and all Arabs knew its meaning, but they did not use it for Allah Ta’ ala. Hence they enquired who and what is Rahman (رَّحْمَـٰنُ ).
