And warn by the Qur'an those who fear that they will be gathered before their Lord - for them besides Him will be no protector and no intercessor - that they might become righteous. 51 Do not turn away those who supplicate their Lord morning and evening, seeking His magnificence. You are not accountable for them in the least, nor they for you at all. If you drive them away you will only be unjust. 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 Thus do We explain the signs in detail: that the way of the sinners may be shown up. 55
