Quran 25:60 — The Statute Book (Al-Furqan)

وَإِذا قيلَ لَهُمُ اسجُدوا لِلرَّحمٰنِ قالوا وَمَا الرَّحمٰنُ أَنَسجُدُ لِما تَأمُرُنا وَزادَهُم نُفورًا

When they are told, "Fall prostrate before the Most Gracious," they say, "What is the Most Gracious? Shall we prostrate before what you advocate?" Thus, it only augments their aversion.

[25:59] He is the One who created the heavens and the earth, and everything between them, in six days, then assumed all authority. The Most Gracious; ask about Him those who are well founded in knowledge.

[25:61] Most blessed is the One who placed constellations in the sky, and placed in it a lamp, and a shining moon.
