Quran 6:88 Al-An'am, ayah 88 of 165

ذَٰلِكَ هُدَى ٱللَّهِ يَهْدِى بِهِۦ مَن يَشَآءُ مِنْ عِبَادِهِۦ ۚ وَلَوْ أَشْرَكُوا۟ لَحَبِطَ عَنْهُم مَّا كَانُوا۟ يَعْمَلُونَ ۝٨٨

6:88 Such is the guidance of Allah wherewith He guideth whom He will of His bondmen. But if they had set up (for worship) aught beside Him, (all) that they did would have been vain.
