Warn those who fear, through this (Qur'an), that they will be gathered before their Lord, and they will have none to protect or intercede for them apart from Him. They may haply take heed for themselves. 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 thus do We detail the verses, and [thus] the way of the criminals will become evident. 55
