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 Why did they not submit themselves (to God) when Our torment struck them. Instead, their hearts were hardened and Satan made their evil deeds seem attractive to them. 43 So, when they forgot what they were reminded of; We opened unto them the gates of everything until; when they rejoiced in what they were given, We seized them suddenly, and behold, they were sore confounded. 44 So of the people who did wrong the last remnant was cut off. Praise be to Allah, Lord of the Worlds! 45 Say thou: look ye were Allah to take away your hearing and your sight and seal up your hearts, what god, other than Allah, shall bring them unto you? Behold! how variously We propound the signs, yet they turn aside. 46 Say: "Imagine if the punishment of God were to come unawares, or openly, who will perish but the evil-doers?" 47 We send the messengers only to give good news and to warn: so those who believe and mend (their lives),- upon them shall be no fear, nor shall they grieve. 48 But those who deny Our messages will be seized by nemesis for being disobedient. 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
