Al-A'raf 7:94

Wama arsalna fee qaryatin minnabiyyin illa akhathna ahlaha bilba/sa-iwaddarra-i laAAallahum yaddarraAAoon

And We sent to no city a prophet [who was denied] except that We seized its people with poverty and hardship that they might humble themselves [to Allāh].

We did not send any prophet to a town, but We seized its people with hardship and suffering, so that they may turn humble.
