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, 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 So when they forgot that by which they had been reminded, We opened to them the doors of every [good] thing until, when they rejoiced in that which they were given, We seized them suddenly, and they were [then] in despair. 44 The origins of the unjust people were therefore cut off; and all praise is to Allah, Lord Of The Creation. 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 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 [Our] message-bearers only as heralds of glad tidings and as warners: hence, all who believe and live righteously - no fear need they have, and neither shall they grieve; 48 And (as for) those who reject Our communications, chastisement shall afflict them because they transgressed. 49 Say [O Prophet]: "I do not say unto you, 'God's treasures are with me,'; nor [do I say,] 'I know the things that are beyond the reach of human perception'; nor do I say unto you, 'Behold, I am an angel': I but follow what is revealed to me." Say: "Can the blind and the seeing be deemed equal? Will you not, then, take thought?" 50
