Whenever We sent a Prophet to a habitation, We first afflicted its people with adversity and calamity so that they should humble themselves. Then We changed their adversity for good fortune till they became very prosperous and said, "Our forefathers also had their adversity and prosperity". At last We seized them all of a sudden when they were quite unaware.77 Had the people of the habitations believed and adopted the way of piety, We would have opened the doors of blessings from the heavens and the earth, but they denied the Truth; so We seized them for the evil they had earned. Do the people of the habitations now feel secure. that Our punishment will not come to them all of a sudden at night, while they might be fast asleep? Or, do they feel secure that Our punishment will not smite them all of a sudden during the day while they might be engaged in pastime? Are these people not afraid of Allah's secret plan?78 In fact, only those people are doomed to destruction, who are not afraid of Allah's secret plan.
