﴿ قَالُوا۟ سُبْحَٰنَكَ أَنتَ وَلِيُّنَا مِن دُونِهِم ۖ بَلْ كَانُوا۟ يَعْبُدُونَ ٱلْجِنَّ ۖ أَكْثَرُهُم بِهِم مُّؤْمِنُونَ ﴾

“They will answer: “Limitless art Thou in Thy glory! Thou [alone] art close unto us, not they! Nay, [when they thought that they were worshipping us,] they were but [blindly] worshipping forces concealed from their senses; most of them believed in them.””

They will say ‘Glory be to You exalted above that You should have an associate! You are our Supporter not they in other words as far as we are concerned there are no bonds of association between us and them. Nay bal is to indicate transition rather they used to worship the jinn the devils in other words they used to obey them and agree to worship us; most of them were believers in them’ accepting as truth what these jinn used to say to them.
