53 Say: "O my Servants who have transgressed against their souls! Despair not of the Mercy of Allah. for Allah forgives all sins: for He is Oft-Forgiving, Most Merciful.
54 "Turn ye to our Lord (in repentance) and bow to His (Will), before the Penalty comes on you: after that ye shall not be helped.
55 "And follow the best of (the courses) revealed to you from your Lord, before the Penalty comes on you - of a sudden while ye perceive not!-
56 "Lest the soul should (then) say: 'Ah! Woe is me!- In that I neglected (my duty) towards Allah, and was but among those who mocked!'-
57 "Or (lest) it should say: 'If only Allah had guided me, I should certainly have been among the righteous!'-
58 "Or (lest) it should say when it (actually) sees the penalty: 'If only I had another chance, I should certainly be among those who do good!'
59 "(The reply will be:) 'Nay, but there came to thee my Signs, and thou didst reject them: thou wast Haughty, and became one of those who reject faith!'"
60 On the Day of Judgment wilt thou see those who told lies against Allah.- their faces will be turned black; Is there not in Hell an abode for the Haughty?
61 But Allah will deliver the righteous to their place of salvation: no evil shall touch them, nor shall they grieve.
62 Allah is the Creator of all things, and He is the Guardian and Disposer of all affairs.
