وَلَوْ شَاءَ اللَّهُ لَجَعَلَهُمْ أُمَّةً وَاحِدَةً وَلَٰكِنْ يُدْخِلُ مَنْ يَشَاءُ فِي رَحْمَتِهِ ۚ وَالظَّالِمُونَ مَا لَهُمْ مِنْ وَلِيٍّ وَلَا نَصِيرٍ
If God had pleased He would have made them one community of belief; but He admits whom He please to His grace; yet the sinners have neither friend nor helper.

(Had Allah willed, He could have made them one community) had Allah willed He would have gathered the Jews, Christians and the idolaters in one religion, the religion of Islam, (but Allah bringeth whom He will into His mercy) to His religion: Islam. (And the wrong-doers) the Jews, Christians and idolaters (have no friend) have no relative to assist them (nor helper) to save them from Allah's punishment.
