AND TELL My servants that they should speak in the most kindly manner [unto those who do not share their beliefs]: verily, Satan is always ready to stir up discord between men - for, verily, Satan is man's open foe! 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 Your Lord knows whoever is in the heavens and the earth. We exalted some of the prophets over the others; and to David We gave the Book of Psalms. 55 Tell them: "Call upon those whom you fancy to be (your helpers) instead of Him! They have no power to remove any affliction from you, nor can they shift it (to any other)." 56 Those they invoke themselves seek the way to their Lord, (striving) which one of them shall be nearest (to Him); and hope for His grace, and dread His punishment. Indeed, the punishment of your Lord is to be feared! 57 No city is there, but We shall destroy it before the Day of Resurrection, or We shall chastise it with a terrible chastisement; that is in the Book inscribed. 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 And when We said to you: Surely your Lord encompasses men; and We did not make the vision which We showed you but a trial for men and the cursed tree in the Quran as well; and We cause them to fear, but it only adds to their great inordinacy. 60
