And warn hereby those who fear lest they be gathered unto their Sustainer with none to protect them from Him or to intercede with Him, so that they might become [fully] conscious of Him. 51 And turn not away those who invoke their Lord, morning and afternoon seeking His Face. You are accountable for them in nothing, and they are accountable for you in nothing, that you may turn them away, and thus become of the Zalimun (unjust). 52 Thus We have tried some of them with others, that they might say: "Is it these (poor believers) that Allah has favoured from amongst us?" Does not Allah know best those who are 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 thus do We explain the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) in detail, that the way of the Mujrimun (criminals, polytheists, sinners), may become manifest. 55
