The word(s) "shaitan" appears 77 time(s) in 67 verse(s) in Quran in Mohsin Khan translation.

(41) 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 a state of conflict and disagreements among them. Surely, shaitan (Satan) is to man a plain enemy.

(42) He said: "Do you remember when we betook ourselves to the rock? I indeed forgot the fish; none but shaitan (Satan) made me forget to remember it. It took its course into the sea in a strange (way)!"

(43) "O my father! Worship not shaitan (Satan). Verily shaitan (Satan) has been a rebel against the Most Gracious (Allah).

(44) "O my father! Verily I fear lest a torment from the Most Gracious (Allah) should overtake you, so that you become a companion of shaitan (Satan) (in the Hell-fire)." [Tafsir Al-Qurtubi]

(45) Then shaitan (Satan) whispered to him, saying: "O Adam! Shall I lead you to the Tree of Eternity and to a kingdom that will never waste away?"

(46) And among mankind is he who disputes concerning Allah, without knowledge, and follows every rebellious (disobedient to Allah) shaitan (devil) (devoid of every kind of good).

(47) Truly, Allah defends those who believe. Verily, Allah likes not any treacherous ingrate to Allah [those who disobey Allah but obey shaitan (Satan)].

(48) Never did We send a Messenger or a Prophet before you but when he did recite the revelation or narrated or spoke, shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise:

(49) That He (Allah) may make what is thrown in by shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimun (polytheists and wrong-doers) are in an opposition far-off (from the truth against Allah's Messenger and the believers).

(50) O you who believe! Follow not the footsteps of shaitan (Satan). And whosoever follows the footsteps of shaitan (Satan), then, verily he commands Al-Fahsha' [i.e. to commit indecency (illegal sexual intercourse)], and Al-Munkar [disbelief and polytheism (i.e. to do evil and wicked deeds; and to speak or to do what is forbidden in Islam)]. And had it not been for the Grace of Allah and His Mercy on you, not one of you would ever have been pure from sins. But Allah purifies (guides to Islam) whom He wills, and Allah is All-Hearer, All-Knower.
