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 And even so do We try some of them by others, that they say: Are these they whom Allah favoureth among us? Is not Allah best Aware of the thanksgivers? 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 Thus We expound revelations so that the way of the culprits may be shown up. 55
