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 Yet why did they not, when Our punishment came to them, humble themselves? But their hearts hardened and the Shaitan made what they did fair-seeming to them. 43 So when they forgot the advices made to them, We opened the gates of all things for them; to the extent that when they were rejoicing for what they had received, We seized them suddenly, hence they remained dejected. 44 The wrongdoers were thus annihilated. All praise be to God, the Lord of the Worlds. 45 Say: "Imagine if God takes away your hearing and sight, and sets a seal on your hearts, what deity other than God will restore them to you?" See how We inflect Our signs: Even then they turn aside. 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 We send the messengers only to give good news and to warn, so those who believe and reform themselves need have no fear, nor will they grieve. 48 Chastisement will befall those who reject Our signs because of their disobedience. 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
