Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 Then why did they not submit when Our punishment came upon them? But their hearts were hardened, and Satan made things they were doing look attractive to them. 43 Then when they forgot that whereof they were reminded We opened upon them the doors of everything, until when they boasted of that which they were given, We laid hold of them on a sudden, and lo! they were dumbfounded. 44 The origins of the unjust people were therefore cut off; and all praise is to Allah, Lord Of The Creation. 45 Say: "Think ye, if Allah took away your hearing and your sight, and sealed up your hearts, who - a god other than Allah - could restore them to you?" See how We explain the signs by various (symbols); yet they turn aside. 46 Say: Can ye see yourselves, if the punishment of Allah come upon you unawares or openly? Would any perish save wrongdoing folk? 47 And We send not apostles but as announcers of good news and givers of warning, then whoever believes and acts aright, they shall have no fear, nor shall they grieve. 48 whereas those who give the lie to Our messages - suffering will afflict them in result of all their sinful doings. 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
