We have sent already unto peoples that were before thee, and We visited them with tribulation and adversity, in order that they might grow humble. 42 If only, when Our disaster came on them, they had been humble! But their hearts were hardened and the devil made all that they used to do seem fair unto them! 43 But when they forgot the warning they had received, We opened to them the gates of all (good) things, until, in the midst of their enjoyment of Our gifts, on a sudden, We called them to account, when lo! they were plunged in despair! 44 So the people that committed wrong were eliminated. And praise to Allah, Lord of the worlds. 45 Say: Have you considered that if Allah takes away your hearing and your sight and sets a seal on your hearts, who is the god besides Allah that can bring it to you? See how We repeat the communications, yet they turn away. 46 Say: 'What do you see yourselves then, if the punishment of Allah overtook you suddenly or openly, would any perish but the harmdoing nation' 47 And We send not the messengers except as bringers of good tidings and warners. So whoever believes and reforms - there will be no fear concerning them, nor will they grieve. 48 But those who deny Our verses - the punishment will touch them for their defiant disobedience. 49 Say [O Prophet]: "I do not say unto you, 'God's treasures are with me,'; nor [do I say,] 'I know the things that are beyond the reach of human perception'; nor do I say unto you, 'Behold, I am an angel': I but follow what is revealed to me." Say: "Can the blind and the seeing be deemed equal? Will you not, then, take thought?" 50
