Preach the Quran to those who are concerned about the Day of Judgment at which time they will be brought before their Lord. Tell them that their only guardian and intercessor is God so that they may become pious. 51 And do not drive away those who call upon their Lord at morning and evening desiring His countenance; nothing of their account falls upon thee, and nothing of thy account falls upon them, that thou shouldst drive them away, and so become one of the evildoers. 52 Thus We have tried some of them with others, that they might say: "Is it these (poor believers) that Allah has favoured from amongst us?" Does not Allah know best those who are grateful? 53 And when those who believe in Our revelations come unto thee, say: Peace be unto you! Your Lord hath prescribed for Himself mercy, that whoso of you doeth evil through ignorance and repenteth afterward thereof and doeth right, (for him) lo! He is Forgiving, Merciful. 54 Thus We distinguish Our signs, that the sinners' way may be manifest. 55
