Tell My servants, (O Muhammad), to say always that which is best. Verily it is Satan who sows discord among people. Satan indeed is an open enemy to mankind. 53 It is your Lord that knoweth you best: If He please, He granteth you mercy, or if He please, punishment: We have not sent thee to be a disposer of their affairs for them. 54 And your Lord is most knowing of whoever is in the heavens and the earth. And We have made some of the prophets exceed others [in various ways], and to David We gave the book [of Psalms]. 55 Say: Call on those whom you assert besides Him, so they shall not control the removal of distress from you nor (its) transference. 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 And [bear in mind:] there is no community which We will not destroy before the Day of Resurrection, or chastise [even earlier, if it proves sinful,] with suffering severe: all this is laid down in Our decree. 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 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
