At-Talaq 65:7

Liyunfiq thoo saAAatin min saAAatihiwaman qudira AAalayhi rizquhu falyunfiq mimma atahuAllahu la yukallifu Allahu nafsan illama ataha sayajAAalu AllahubaAAda AAusrin yusra

Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allāh has given him. Allāh does not charge a soul except [according to] what He has given it. Allāh will bring about, after hardship, ease [i.e., relief].

A man of vast means should spend according to his vast means. And anyone whose sustenance is limited should spend from whatever Allah has given to him. Allah makes no one liable beyond what He has given to him. Allah will soon bring ease after a difficulty.
