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 knows you best. He will have mercy on you if He wills and chastise you if He wills. We have not sent you, (O Muhammad), as an overseer over them. 54 And thy Lord is Best Aware of all who are in the heavens and the earth. And we preferred some of the prophets above others, and unto David We gave the Psalms. 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 call upon are themselves seeking a means to come to their Lord, competing with each other to be nearer; they hope for His Mercy and fear His punishment. Indeed, the punishment of your Lord is the subject of caution. 57 The decree that all the towns were to be destroyed or afflicted with severe punishment was already written in the Book before the Day of Judgment. 58 Nothing could stop Us from sending signs except that the earlier people had rejected them as lies. We sent to Thamud the she-camel as a token to make it clear to them, but they treated her cruelly; and We send signs only to deter. 59 We told you that your Lord encompasses mankind. We granted the vision which We showed you, as well as the tree that is cursed in the Quran, only as a test for mankind. We warn them, but this only increases their insolence. 60
