وَلَوْ شَاء اللَّهُ لَجَعَلَهُمْ أُمَّةً وَاحِدَةً وَلَكِن يُدْخِلُ مَن يَشَاء فِي رَحْمَتِهِ وَالظَّالِمُونَ مَا لَهُم مِّن وَلِيٍّ وَلَا نَصِيرٍ
﴿٨﴾
سورة الشورى
(42/8) And if Allah had willed, He would surely have made them a single nation. And but He makes whom He wills enter into His Mercy, and for the wrong-doers, there is no friend, nor helper for them.
Surah Ash-Shura
