And We did indeed send Messengers to other nations before you and then We seized those nations with misfortune and hardship so that they might humble themselves (before Us). 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 As such the harmdoers were annihilated. Praise be to Allah, Lord of the Worlds! 45 (Muhammad), ask them, "Have you ever considered that if God was to disable your hearing and vision and veil your hearts, could anyone besides Him restore them?" Look at how plainly We show them the evidence (of the Truth) but they always ignore it. 46 Say: 'What think you? If God's chastisement comes upon you, suddenly or openly, shall any be destroyed, except the people of the evildoers?' 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 And those who belie Our signs - torment shall touch them for they have been transgressing. 49 (O Muhammad!) Say: 'I do not say to you I have the treasures of Allah. Nor do I have knowledge of what is beyond the reach of human perception. Nor do I say to you: I am an angel. I only follow what is revealed to me.' Then ask them: 'Are the blind and the seeing alike?' Do you not then reflect? 50
