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 Do not disregard those who pray to their Lord in the mornings and evenings, seeking their Lord's pleasure. You will not be held responsible for them nor will they be held responsible for you. Do not disregard them lest you become 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 And when those who believe in Our communications come to you, say: Peace be on you, your Lord has ordained mercy on Himself, (so) that if any one of you does evil in ignorance, then turns after that and acts aright, then He is Forgiving, Merciful. 54 And this is how We explain Our verses clearly and so that the way of the criminals become well exposed. 55
