Does God bestow special favor upon the poor people as well as the true believers?

Verses 79-82 of Chapter 18:
As for the boat, it belonged to poor people working in the sea. So I wished to make a defective damage in it, as there was a king behind them who seized every boat by force. And as for the boy, his parents were believers, and we feared he would oppress them by rebellion and disbelief. So we intended that their Lord should exchange him for them for one better in righteousness and nearer to mercy. And as for the wall, it belonged to two orphan boys in the town; and there was under it a treasure belonging to them; and their father was a righteous man, and your Lord intended that they should attain their age of full strength and take out their treasure as a mercy from your Lord. And I did them not of my own accord. That is the interpretation of those (things) over which you could not be patient.
