وَلَوْ شَاءَ اللَّهُ لَجَعَلَكُمْ أُمَّةً وَاحِدَةً وَلَٰكِنْ يُضِلُّ مَنْ يَشَاءُ وَيَهْدِي مَنْ يَشَاءُ ۚ وَلَتُسْأَلُنَّ عَمَّا كُنْتُمْ تَعْمَلُونَ

Surah An-Nahl : 93
And if Allah had willed, He could have made you [of] one religion, but He causes to stray whom He wills and guides whom He wills. And you will surely be questioned about what you used to do.
