Surah An-Nahl, Verse 93

وَلَوۡ شَآءَ ٱللَّهُ لَجَعَلَكُمۡ أُمَّةٗ وَٰحِدَةٗ وَلَٰكِن يُضِلُّ مَن يَشَآءُ وَيَهۡدِي مَن يَشَآءُۚ وَلَتُسۡـَٔلُنَّ عَمَّا كُنتُمۡ تَعۡمَلُونَ٩٣

walaw shāa l-lahu lajaʿalakum ummatan wāḥidatan walākin yuḍillu man yashāu wayahdī man yashāu walatus'alunna ʿammā kuntum taʿmalūna

And if Allāh had willed, He could have made you [of] one religion, but He sends astray whom He wills and guides whom He wills. And you will surely be questioned about what you used to do.
