Surah Ash-Shura Verse 8 - English Translation by A. J. Arberry
Surah Ash-Shuraوَلَوۡ شَآءَ ٱللَّهُ لَجَعَلَهُمۡ أُمَّةٗ وَٰحِدَةٗ وَلَٰكِن يُدۡخِلُ مَن يَشَآءُ فِي رَحۡمَتِهِۦۚ وَٱلظَّـٰلِمُونَ مَا لَهُم مِّن وَلِيّٖ وَلَا نَصِيرٍ
If God had willed, He would have made them one nation; but He admits whomsoever He will into His mercy, and the evildoers shall have neither protector nor helper
