And warn therewith those who fear they shall be mustered to their Lord; they have, apart from God, no protector and no intercessor; haply they will be godfearing. 51 And do not drive away those who call upon their Lord at morning and evening desiring His countenance; nothing of their account falls upon thee, and nothing of thy account falls upon them, that thou shouldst drive them away, and so become one of the evildoers. 52 For it is in this way that We try men through one another - to the end that they might ask, "Has God, then, bestowed His favour upon those others in preference to us?" Does not God know best as to who is grateful [to Him]? 53 When those who believe in Our revelations come to you, say, "Peace be upon you. Your Lord has taken it upon Himself to be merciful. So that if any one among you does evil in ignorance and repents thereafter and makes amends, then He is most forgiving and ever merciful." 54 Thus do We explain Our revelations so that the sinful way can be plainly discerned. 55
