The verse implies that the believers were of opinion that, through their mere FAITH, they could obtain salvation and enter the Paradise without any good work and action. The verse denied them that, saying: ``Did you think that you would enter the Garden of Bliss without such trials as came to those who passed away before you; while they encountered many hardship and suffering, and were so shaken in spirit that even the prophets and those who believed with them cried: When the help of God may come?''
Of course they did not issue that word through objection, but as a request and their wish. This verse points at one of the everlasting Divine rules and customs; that in all ages the believers have to work hard for salvation, and encounter sufferings and hardship, if they are willing to enter the Paradise. In other word: ``NO PAIN, NO GAIN''
