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 do not send away those who call upon their Lord morning and afternoon, seeking His countenance. Not upon you is anything of their account and not upon them is anything of your account. So were you to send them away, you would [then] be of the wrongdoers. 52 In this way We try some of them by means of others, so that they may ask, "Are these [lowly ones] whom God has singled out for His favours from among us? Does God not know best who are the grateful ones?" 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
