ذَٰلِكَ هُدَى اللَّهِ يَهْدِي بِهِ مَنْ يَشَاءُ مِنْ عِبَادِهِ ۚ وَلَوْ أَشْرَكُوا لَحَبِطَ عَنْهُمْ مَا كَانُوا يَعْمَلُونَ 88
This is the guidance of Allah: He giveth that guidance to whom He pleaseth, of His worshippers. If they were to join other gods with Him, all that they did would be vain for them.
