And As Soon As They Are Overwhelmed By Waves Like Mountains
Secondly your question is not very clear to me. How there is harassment in the verse. Allah designed this universe and all the events. When a person goes through near death experience, the person by its own will start accepting existence of a creator and begs for his mercy and help to survive. This is both believers and nonbelievers do. The difference between a believers and nonbelievers is that when believers are saved, they thank Allah and their faith gets stronger. In contrast when disbelievers are saved, they just forget Allah who saved them and return to doing shirk and sins as if nothing happened.
