And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us]. 42 if only, when Our might came upon them, they had been humble! But their hearts were hard, and Satan decked out fair to them what they were doing. 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 So the roots of the people who did wrong were cut off. And all the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinns, and all that exists). 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: "Can you imagine what your condition will be if God's chastisement befalls you, either suddenly or in a [gradually] perceptible manner? [But then - ] will any but evildoing folk [ever] be destroyed? 47 And We did not send Noble Messengers except as Heralds of glad tidings and warnings; so upon those who accept faith and reform themselves, shall be no fear nor shall they grieve. 48 But those who belie Our verses, punishment shall touch them for their misdeeds. 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
