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 drive away those who call upon their Lord in the morning and the evening, they desire only His favor; neither are you answerable for any reckoning of theirs, nor are they answerable for any reckoning of yours, so that you should drive them away and thus be of the unjust. 52 And even so do We try some of them by others, that they say: Are these they whom Allah favoureth among us? Is not Allah best Aware of the thanksgivers? 53 When those who believe in Our verses come to you, say: 'Peace be upon you. Your Lord has decreed Mercy on Himself, if any one of you commits evil through ignorance, and then repents, and mends his ways, then He is Forgiving, the Most Merciful' 54 Thus We make plain Our signs, so that the path of the evil-doers might be laid bare. 55
