Warn by it those who fear to be gathered before their Lord, when they have no guardian or intercessor besides God, so that they may become God-fearing. 51 Send not away those who call on their Lord morning and evening, seeking His face. In naught art thou accountable for them, and in naught are they accountable for thee, that thou shouldst turn them away, and thus be (one) of the unjust. 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 the signs in detail: that the way of the sinners may be shown up. 55
