And say to My slaves (i.e. the true believers of Islamic Monotheism) that they should (only) say those words that are the best. (Because) Shaitan (Satan) verily, sows disagreements among them. Surely, Shaitan (Satan) is to man a plain enemy. 53 Your Lord is the Best Knower of you; if He willeth He will have mercy upon you, or if He willeth He will torment you. And We have not sent thee over them as a trustee. 54 And your Lord knows best all who are in the heavens and the earth. And indeed, We have preferred some of the Prophets above others, and to Dawud (David) We gave the Zabur (Psalms). 55 Say: 'Call on those you asserted apart from Him; they have no power to remove affliction from you, or to transfer it. 56 The devoted bondmen whom these disbelievers worship, themselves seek the means of proximity from their Lord, that who among them is the closest (to his Lord), and hope for His mercy and fear His punishment; indeed the punishment of your Lord is to be feared. 57 There is not a population but We shall destroy it before the Day of Judgment or punish it with a dreadful Penalty: that is written in the (eternal) Record. 58 Naught prevented Us from sending the signs but that the ancients cried lies to them; and We brought Thamood the She-camel visible, but they did her wrong. And We do not send the signs, except to frighten. 59 When We said to you: "Verily your Lord circumscribes mankind," and showed you the vision and the accursed tree of the Qur'an, it was as a bone of contention for men. Thus do We (instil) fear in them; but they only transgress the more. 60
