Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 When the affliction decreed by Us befell them, they did not humble themselves, but rather their hearts hardened, for Satan had made all their doings seem fair 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 Then the people who committed wrong were cut off completely. And all praise is unto Allah, 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: "Think ye, if the punishment of Allah comes to you, whether suddenly or openly, will any be destroyed except those who do wrong? 47 We did not send the Messengers for any other reason than to bring (people) the glad news (of God's mercy) and to warn (them of the torment brought on by disobedience to God). Whoever accepts the faith and lives a righteous life will have nothing to fear, nor will he be grieved. 48 But those who reject Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.), the torment will touch them for their disbelief (and for their belying the Message of Muhammad SAW). [Tafsir Al-Qurtubi]. 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
