Quran An-Nahl 16:93
وَلَوۡ شَآءَ ٱللَّهُ لَجَعَلَكُمۡ أُمَّةٗ وَٰحِدَةٗ وَلَٰكِن يُضِلُّ مَن يَشَآءُ وَيَهۡدِي مَن يَشَآءُۚ وَلَتُسۡـَٔلُنَّ عَمَّا كُنتُمۡ تَعۡمَلُونَ ٩٣
Translation
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.
