وَلَوْ شَاء اللَّهُ لَجَعَلَهُمْ أُمَّةً وَاحِدَةً وَلَكِن يُدْخِلُ مَن يَشَاء فِي رَحْمَتِهِ وَالظَّالِمُونَ مَا لَهُم مِّن وَلِيٍّ وَلَا نَصِيرٍ
[42:8]
And if Allah had pleased He would surely have made them a single community, but He makes whom He pleases enter into His mercy, and the unjust it is that shall have no guardian or helper.
If Allah had so willed, He could have made them a single people; but He admits whom He will to His Mercy; and the Wrong-doers will have no protector nor helper.
Had Allah willed, He could have made them one community, but Allah bringeth whom He will into His mercy. And the wrong-doers have no friend nor helper.
