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 yet when the misfortune decreed by Us befell them, they did not humble themselves, but rather their hearts grew hard, for Satan had made all their doings seem goodly to them. 43 When they forgot (all) the advice that they had received, We granted them all means of happiness but they were left in despair when We suddenly took Our bounties back from them. 44 Thus, the transgressing people were destroyed. It is only God, the Lord of creation who deserves all praise. 45 Say: "Think ye, if Allah took away your hearing and your sight, and sealed up your hearts, who - a god other than Allah - could restore them to you?" See how We explain the signs by various (symbols); yet they turn aside. 46 Say: 'What do you see yourselves then, if the punishment of Allah overtook you suddenly or openly, would any perish but the harmdoing nation' 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 whereas those who give the lie to Our signs, chastisement will visit them for their transgression. 49 Say (O Muhammad SAW): "I don't tell you that with me are the treasures of Allah, nor (that) I know the unseen; nor I tell you that I am an angel. I but follow what is revealed to me by inspiration." Say: "Are the blind and the one who sees equal? will you not then take thought?" 50
