Allah (SWT) created all creatures and He provides all of them whether they believe and obey Him or not. That is from His Great Mercy. Some believers suffer from poverty because of injustice of oppressors or any other reason. Poverty can also in certain cases be a test to purify the believer or elevate his degree.
Poverty is not degradation and wealth is not an honor. Both are tests.
Many enemies of Allah were granted wealth like Firaon ( Pharaoh) and Hamaan and Qaroun (Korah) while many Prophets were tested by poverty and illness like Prophet Ayyub (AS).
Wassalam.
