Surah An-Nahl, ayah 93

وَلَوۡ شَآءَ ٱللَّهُ لَجَعَلَكُمۡ أُمَّةٗ وَٰحِدَةٗ وَلَٰكِن يُضِلُّ مَن يَشَآءُ وَيَهۡدِي مَن يَشَآءُۚ وَلَتُسۡـَٔلُنَّ عَمَّا كُنتُمۡ تَعۡمَلُونَ ٩٣

Walaw shā'allāhu laja'alakum ummatan wāhidatan walākin yudillu man yashā'u wayahdī man yashā'u walatus'alunna 'ammā kuntum ta'malūn

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.⁷¹³ And you will surely be questioned about what you used to do.
