That religion to which they were guided is God’s guidance wherewith He guides whom He will of His servants; had they hypothetically speaking been idolaters all that they did would have been in vain.
- 6:8888
ذَٰلِكَ هُدَى اللَّهِ يَهْدِي بِهِ مَنْ يَشَاءُ مِنْ عِبَادِهِ ۚ وَلَوْ أَشْرَكُوا لَحَبِطَ عَنْهُمْ مَا كَانُوا يَعْمَلُونَ
This is the Guidance of Allah with which He guides whomsoever He will of His slaves. But if they had joined in worship others with Allah, all that they used to do would have been of no benefit to them.
