An-Nahl 16:71

Wallahu faddala baAAdakumAAala baAAdin fee arrizqi fama allatheenafuddiloo biraddee rizqihim AAala mamalakat aymanuhum fahum feehi sawaon afabiniAAmatiAllahi yajhadoon

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. Then is it the favor of Allāh they reject?

Allah has given some of you preference over others in provision. So, those given preference are not willing to pass on their provision to their slaves, so that they become equal in it: Do they, then, reject the blessing of Allah?
