Warn hereby those who fear (because they know) that they will be gathered unto their Lord, for whom there is no protecting ally nor intercessor beside Him, that they may ward off (evil). 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 We have made some of them a means for testing others so that they should say: 'Are these the ones among us upon whom Allah has bestowed His favour?' Yes, does Allah not know well who are the thankful? 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 We distinguish Our signs, that the sinners' way may be manifest. 55
