8وَلَو شاءَ اللَّهُ لَجَعَلَهُم أُمَّةً واحِدَةً وَلٰكِن يُدخِلُ مَن يَشاءُ في رَحمَتِهِ ۚ وَالظّالِمونَ ما لَهُم مِن وَلِيٍّ وَلا نَصيرٍ(Irfan-ul-Quran)And had Allah so willed, He would have made all of them a single community. But He admits to His Mercy whom He likes. And for the wrongdoers there will be no protector or guardian.
