Chapter 42 Sign 8

وَلَوۡ شَآءَ ٱللَّهُ لَجَعَلَهُمۡ أُمَّةٗ وَٰحِدَةٗ وَلَٰكِن يُدۡخِلُ مَن يَشَآءُ فِي رَحۡمَتِهِۦۚ وَٱلظَّٰلِمُونَ مَا لَهُم مِّن وَلِيّٖ وَلَا نَصِيرٍ٨

And if wished the God, to be making them people one, and but He admits who He wishes in His mercy. And the wrongdoers, not to them from protector and not helper.
