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 knows you very well; if He will, He will have mercy on you, or, if He will, He will chastise you. We sent thee not to be a guardian over them. 54 We have given preference to some Prophets over others and We gave the psalms to David. 55 Say: "Call those whom you imagine to be gods besides Him; yet they have no power to relieve you of any distress or to avert it." 56 Those [saintly beings] whom they invoke are themselves striving to obtain their Sustainer's favour - [even] those among them who are closest [to Him] - hoping for His grace and dreading His chastisement: for, verily, thy Sustainer's chastisement is something to beware of! 57 And there is not a town but We will destroy it before the day of resurrection or chastise it with a severe chastisement; this is written in the Divine ordinance. 58 And nothing has prevented Us from sending signs except that the former peoples denied them. And We gave Thamud the she-camel as a visible sign, but they wronged her. And We send not the signs except as a warning. 59 (Muhammad), We told you that your Lord has encompassed all mankind. We made the vision which We showed you and the condemned tree, mentioned in the Quran, as a trial for the human being. Even though We warn them, it only increases their rebellion. 60
