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 Repel not those who call upon their Lord at morn and evening, seeking His Countenance. Thou art not accountable for them in aught, nor are they accountable for thee in aught, that thou shouldst repel them and be of the wrong-doers. 52 Thus do We try men through one another so that they may ask: "Are these the ones of all of us who have been favoured by God?" Does God not know who are the grateful? 53 When those who believe in Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) come to you, say: "Salamun 'Alaikum" (peace be on you); your Lord has written Mercy for Himself, so that, if any of you does evil in ignorance, and thereafter repents and does righteous good deeds (by obeying Allah), then surely, He is Oft-Forgiving, Most Merciful. 54 And this is how We explain Our verses clearly and so that the way of the criminals become well exposed. 55
