16:93
وَلَوْ شَٓاءَ اللّٰهُ لَجَعَلَكُمْ اُمَّةً وَاحِدَةً وَلٰكِنْ یُضِلُّ مَنْ یَشَٓاءُ وَیَهْدٖی مَنْ یَشَٓاءُؕ وَلَتُسْـَٔلُنَّ عَمَّا كُنْتُمْ تَعْمَلُونَ
Walaw shaa Allahu lajaAAalakum ommatan wahidatan walakin yudillu man yashao wayahdee man yashao walatusalunna AAamma kuntum taAAmaloona
Translations
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
Saheeh International
Had Allah willed He could have made you (all) one nation, but He sendeth whom He will astray and guideth whom He will, and ye will indeed be asked of what ye used to do
