And say to My servants (that) they speak that which is best; surely the Shaitan sows dissensions among them; surely the Shaitan is an open enemy to man. 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 We have given preference to some Prophets over others and We gave the psalms to David. 55 Say thou: call upon those whom ye fancy beside Him; they are able neither to remove the distress from you nor to work a turning off. 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 There is not a habitation We shall not destroy before the Day of Resurrection, or not inflict severe punishment upon it. This is in accordance with the law (of God). 58 Naught hindereth Us from sending portents save that the folk of old denied them. And We gave Thamud the she-camel - a clear portent save to warn. 59 And (remember) when We told you: "Verily! Your Lord has encompassed mankind (i.e. they are in His Grip)." And We made not the vision which we showed you (O Muhammad as an actual eye-witness and not as a dream on the night of Al-Isra') but a trial for mankind, and likewise the accursed tree (Zaqqum, mentioned) in the Quran. We warn and make them afraid but it only increases them in naught save great disbelief, oppression and disobedience to Allah. 60
