And the evils of that which they earned will become apparent to them, and that which they used to mock at will encircled them. (48) When harm touches man, he calls to Us (for help), then when We have (rescued him from that harm and) changed it into a favour from Us, he says: "Only because of knowledge (that I possess) I obtained it." Nay, it is only a trial, but most of them know not! (49) Verily, those before them said it, yet (all) that they had earned availed them not. (50) So, the evil results of that which they earned overtook them. And those who did wrong of these [people to whom you (Muhammad SAW) have been sent], will also be overtaken by the evil results (torment) for that which they earned, and they will never be able to escape[]. (51) Do they not know that Allâh enlarges the provision for whom He wills, and straitens it (for whom He wills). Verily, in this are signs for the folk who believe! (52) Say: "O 'Ibâdî (My slaves) who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the Mercy of Allâh, verily Allâh forgives all sins. Truly, He is Oft-Forgiving, Most Merciful[] (53) "And turn in repentance and in obedience with true Faith (Islâmic Monotheism) to your Lord and submit to Him, (in Islâm), before the torment comes upon you, (and) then you will not be helped. (54) "And follow the best of that which is sent down to you from your Lord (i.e. this Qur'ân, do what it orders you to do and keep away from what it forbids), before the torment comes on you suddenly while you perceive not!" (55) Lest a person should say: "Alas, my grief that I was undutiful to Allâh (i.e. I have not done what Allâh has ordered me to do), and I was indeed among those who mocked [at the truth! i.e. Lâ ilâha illallâh (none has the right to be worshipped but Allâh), the Qur'ân, and Muhammad SAW and at the faithful believers] (56)
