And say to My slaves (i.e. the true believers of Islamic Monotheism) that they should (only) say those words that are the best. (Because) Shaitan (Satan) verily, sows disagreements among them. Surely, Shaitan (Satan) is to man a plain enemy. 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 seeing that thy Sustainer is fully aware of [what is in the minds of] all beings that are in the heavens and on earth. But, indeed, We did endow some of the prophets more highly than others - just as We bestowed upon David a book of divine wisdom [in token of Our grace] 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 And recall what time We said unto thee: verily thy Lord hath encompassed mankind. And We made the vision We shewed thee but a temptation for men, and likewise the tree accurst in the Qur'an. And We frighten them, but it only increaseth them in exorbitance great. 60
