And warn with it those who fear that they shall be gathered to their Lord-- there is no guardian for them, nor any intercessor besides Him-- that they may guard (against evil). 51 And do not drive away those who call upon their Lord in the morning and the evening, they desire only His favor; neither are you answerable for any reckoning of theirs, nor are they answerable for any reckoning of yours, so that you should drive them away and thus be of the unjust. 52 Even so We have tried some of them by others that they may say, Are these the ones God has been gracious to among us?' Knows not God very well the thankful? 53 And when those who believe in Our signs come unto them, say thou: peace be on you; your Lord hath prescribed mercy for Himself; so that whosoever of you doeth an evil through ignorance, then repenteth thereafter and amendeth, then verily He is Forgiving, Merciful. 54 Thus do We expound the revelations that the way of the unrighteous may be manifest. 55
