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 disaster came on them, they had been humble! But their hearts were hardened and the devil made all that they used to do seem fair unto 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 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, "Have you considered: if Allah should take away your hearing and your sight and set a seal upon your hearts, which deity other than Allah could bring them [back] to you?" Look how we diversify the verses; then they [still] 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 sent ones except as bearers of glad tidings and warners. Then whosoever believeth and amendeth, on such shall come no fear nor they shall grieve. 48 Chastisement will befall those who reject Our signs because of their disobedience. 49 Say: 'I do not tell you that I have the treasuries of Allah or know the unseen, nor do I claim to be an angel. I follow only that which is revealed to me' Say: 'Are the blind and the seeing alike? Will you not think' 50
