The Ornaments of Gold - 43:32
Do they divide the mercy of your Lord? We divided between them their livelihood in the life of this world, and We made them superior to one another in rank, so that they might cause one another to work. And the mercy of your Lord is better than what they have accumulated.
Our Lord exalts us over one another in degrees, to test us with what He has given:
The Cattle/6:165
He has made you inheritors of the earth, and He has made some of you superior to others in degrees, that He may try you with what He has given you. Your Lord is the quick-finishing. Forgiving, Merciful.
The Bee/16:71
Allah has made you superior to one another in sustenance. Indeed, those who are made superior do not share their wealth equally with those under them. Do they reject the Blessing of Allah?
The Night Journey/17:21
Notice how We have made people superior to one another. Greater are the degrees and superiorities of the Hereafter
The Ornaments of Gold/43:32
Do they divide the mercy of your Lord? We divided between them their livelihood in the life of this world, and We made them superior to one another in rank, so that they might cause one another to work. And the mercy of your Lord is better than what they have accumulated.
