Verse 93

وَلَوْ شَآءَ ٱللَّهُ لَجَعَلَكُمْ أُمَّةً وَٰحِدَةً وَلَـٰكِن يُضِلُّ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ وَلَتُسْـَٔلُنَّ عَمَّا كُنتُمْ تَعْمَلُونَ

And had God willed He could have made you one single community, however, He misleads whomever He wills and guides whomever He wills. As for you, you will surely be questioned about everything you have done.
