﴿ يُوفُونَ بِٱلنَّذْرِ وَيَخَافُونَ يَوْمًۭا كَانَ شَرُّهُۥ مُسْتَطِيرًۭا ﴾

“[The truly virtuous are] they [who] fulfil their vows, and stand in awe of a Day the woe of which is bound to spread far and wide,”

Man has been created free in this world and then he has been shown two paths leading respectively towards a life of gratitude and a life of ingratitude. Now, it is for the concerned person to choose either of the two paths. For one who adopts the way of ingratitude, there will be the punishment of Hell in the Hereafter, and for one who adopts the way of gratitude, there will be the bounties of Paradise.
