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 Send not away those who call on their Lord morning and evening, seeking His face. In naught art thou accountable for them, and in naught are they accountable for thee, that thou shouldst turn them away, and thus be (one) of the 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 And when those who believe in Our signs come unto them, say thou: peace be on you; your Lord hath prescribed mercy for Himself; so that whosoever of you doeth an evil through ignorance, then repenteth thereafter and amendeth, then verily He is Forgiving, 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
