Surah 6 : Ayah 88

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

This is Allah’s guidance with which He guides whom He wills of His slaves. If they were to associate others with Him, all their deeds would have been nullified.
