Qur'an 42:8 · Ash-Shura

وَلَوْ شَآءَ ٱللَّهُ لَجَعَلَهُمْ أُمَّةًۭ وَٰحِدَةًۭ وَلَٰكِن يُدْخِلُ مَن يَشَآءُ فِى رَحْمَتِهِۦ ۚ وَٱلظَّٰلِمُونَ مَا لَهُم مِّن وَلِىٍّۢ وَلَا نَصِيرٍ

(8) And if Allāh willed, He could have made them [of] one religion, but He admits whom He wills[1409] into His mercy. And the wrongdoers have not any protector or helper.
