The Holy Quran 42:8 — Surah Ash-Shuraa

Arabic text

وَلَوْ شَآءَ ٱللَّهُ لَجَعَلَهُمْ أُمَّةً وَٰحِدَةً وَلَـٰكِن يُدْخِلُ مَن يَشَآءُ فِى رَحْمَتِهِۦ ۚ وَٱلظَّـٰلِمُونَ مَا لَهُم مِّن وَلِىٍّ وَلَا نَصِيرٍ

Translation

If Allaah willed, He would have made them (mankind) a single nation (but Allaah did not do so for reasons He knows best). However, He will enter (admit) whoever he wills into His mercy (by making them Mu'mineen), and (those who remain Kuffaar will be far from His mercy and) there shall be no friend nor assistant (against punishment) for the oppressors (the Kuffaar).

Tafsir (excerpt) — Tafsir Usmani

The difference of religions and communities is by Allah's wisdom: that is, He certainly had the power, had He wished, to make all alike and set them on a single path, but His wisdom required that He manifest both kinds of His attributes, mercy and wrath. Therefore He placed difference and disparity in the states of His servants.
