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 they humbled themselves when Our scourge overtook them! But their hearts were hardened, and satan decorated to them what they were doing. 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, "If God should take away your hearing and your sight and seal your hearts, who is the deity who could restore it to you save God?" See how We explain the signs to them in diverse ways, yet they turn away. 46 Ask them, "Tell me, if the punishment of God came upon you suddenly or predictably, would any but the wrongdoers be destroyed?" 47 And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor shall they grieve. 48 But those who reject our signs,- them shall punishment touch, for that they ceased not from transgressing. 49 Tell them: "I do not say that I possess the treasures of God, or have knowledge of the Unknown, or that I am an angel. I only follow what is sent down to me." And say: "How can a blind man and a man who can see, be alike? Will you not reflect?" 50
