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 Wherefore then did they not, when the affliction from us came upon them, humble themselves? But their hearts became hardened, and the Satan made fair-seeming unto them that which they were wont to do. 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 Thus, the transgressing people were destroyed. It is only God, the Lord of creation who deserves all praise. 45 Say: Have ye imagined, if Allah should take away your hearing and your sight and seal your hearts, Who is the Allah Who could restore it to you save Allah? See how We display the revelations unto them! Yet still they turn away. 46 Say: Have you considered if the chastisement of Allah should overtake you suddenly or openly, will any be destroyed but the unjust people? 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 Those who reject Our revelations will certainly be punished for their evil deeds. 49 (Muhammad), tell them, "I do not claim to have all the treasures of God in my hands, nor to know the unseen, nor do I claim to be an angel. I follow only what is revealed to me (from God)." Say to them, "Are the blind and the seeing equal?" Why then do you not think? 50
