Warn by it those who fear to be gathered before their Lord, when they have no guardian or intercessor besides God, so that they may become God-fearing. 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 thus We have tried some of them through others that the disbelievers might say, "Is it these whom Allah has favored among us?" Is not Allah most knowing of 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
