Surah Ash-Shura Verse 8

وَلَوْ شَاءَ اللَّهُ لَجَعَلَهُمْ أُمَّةً وَاحِدَةً وَلَٰكِن يُدْخِلُ مَن يَشَاءُ فِي رَحْمَتِهِ ۚ وَالظَّالِمُونَ مَا لَهُم مِّن وَلِيٍّ وَلَا نَصِيرٍ

Wa law shaaa'al laahu laja'alahum ummatanw waahi datanw walaakiny yudkhilumany yashaaa'u fee rahmatih; waz zaalimoona maa lahum minw waliyyinw wa laa naseer

Translation / The Meaning

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