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 Then, when they forgot that whereof they had been reminded, We opened unto them the gates of all things till, even as they were rejoicing in that which they were given, We seized them unawares, and lo! they were dumbfounded. 44 Thus, the transgressing people were destroyed. It is only God, the Lord of creation who deserves all praise. 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: 'If the chastisement of Allah were to overtake you unawares or openly shall any except the wrong-doing people be destroyed?' 47 We do not send apostles but to give good tidings and to warn. Then those who believe or reform will have neither fear nor regret. 48 But those who deny Our messages will be seized by nemesis for being disobedient. 49 Say (O Muhammad SAW): "I don't tell you that with me are the treasures of Allah, nor (that) I know the unseen; nor I tell you that I am an angel. I but follow what is revealed to me by inspiration." Say: "Are the blind and the one who sees equal? will you not then take thought?" 50
