The Quran

وَاللَّهُ فَضَّلَ بَعضَكُم عَلىٰ بَعضٍ فِي الرِّزقِ ۚ فَمَا الَّذينَ فُضِّلوا بِرادّي رِزقِهِم عَلىٰ ما مَلَكَت أَيمانُهُم فَهُم فيهِ سَواءٌ ۚ أَفَبِنِعمَةِ اللَّهِ يَجحَدونَ

(Saheeh International)

And Allāh has favored some of you over others in provision. But those who were favored [i.e., given more] would not hand over their provision to those whom their right hands possess [i.e., slaves] so they would be equal to them therein.¹ Then is it the favor of Allāh they reject?

The argument presented in this verse is that if they cannot consider their own possessions equal to themselves, then how can they consider Allāh's creations as being equal to Him?
