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 Your Lord knows you very well. He will have mercy on you if He will, or punish you if He will. We have not sent you to be their guardian. 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 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 unto whom they cry seek the way of approach to their Lord, which of them shall be the nearest; they hope for His mercy and they fear His doom. Lo! the doom of thy Lord is to be shunned. 57 There is not a population but We shall destroy it before the Day of Judgment or punish it with a dreadful Penalty: that is written in the (eternal) Record. 58 And naught hindered Us from sending the signs except that the ancients belied them. And We vouchsafed unto Thamud a she-camel as an illumination, but they did her wrong. And We send not the signs save to frighten. 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
