And certainly We sent (apostles) to nations before you then We seized them with distress and affliction in order that they might humble themselves. 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 roots of the people who were unjust were cut off; and all praise is due to Allah, the 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: "Tell me, if the punishment of Allah comes to you suddenly (during the night), or openly (during the day), will any be destroyed except the Zalimun (polytheists and wrong-doing people)?" 47 And We send not the sent ones except as bearers of glad tidings and warners. Then whosoever believeth and amendeth, on such shall come no fear nor they shall grieve. 48 And (as for) those who reject Our communications, chastisement shall afflict them because they transgressed. 49 Say (O Muhammad, to the disbelievers): I say not unto you (that) I possess the treasures of Allah, nor that I have knowledge of the Unseen; and I say not unto you: Lo! I am an angel. I follow only that which is inspired in me. Say: Are the blind man and the seer equal? Will ye not then take thought? 50
