The word(s) "worship" appears 429 time(s) in 354 verse(s) in Quran in Mohsin Khan translation.

(81) Say (O Muhammad صلى الله عليه وسلم): My Lord has commanded justice and (said) that you should face Him only (i.e. worship none but Allah and face the Qiblah, i.e. the Ka'bah at Makkah during prayers) in every place of worship, in prayers (and not to face other false deities and idols), and invoke Him only making your religion sincere to Him (by not joining in worship any partner with Him and with the intention that you are doing your deeds for Allah's sake only). As He brought you (into being) in the beginning, so shall you be brought into being [on the Day of Resurrection in two groups, one as a blessed one (believers), and the other as a wretched one (disbelievers)].

(82) Say (O Muhammad صلى الله عليه وسلم): "(But) the things that my Lord has indeed forbidden are Al-Fawahish (great evil sins and every kind of unlawful sexual intercourse) whether committed openly or secretly, sins (of all kinds), unrighteous oppression, joining partners (in worship) with Allah for which He has given no authority, and saying things about Allah of which you have no knowledge."

(83) Who is more unjust than one who invents a lie against Allah or rejects His Ayat (proofs, evidence, verses, lessons, signs, revelations)? For such their appointed portion (good things of this worldly life and their period of stay therein) will reach them from the Book (of Decrees) until when Our Messengers (the angel of death and his assistants) come to them to take their souls, they (the angels) will say: "Where are those whom you used to invoke and worship besides Allah," they will reply, "They have vanished and deserted us." And they will bear witness against themselves, that they were disbelievers.

(84) Await they just for the final fullfilment of the event? On the Day the event is finally fulfilled (i.e. the Day of Resurrection), those who neglected it before will say: "Verily, the Messengers of our Lord did come with the truth, now are there any intercessors for us that they might intercede on our behalf? Or could we be sent back (to the first life of the world) so that we might do (good) deeds other than those (evil) deeds which we used to do?" Verily, they have lost their ownselves (i.e. destroyed themselves) and that which they used to fabricate (invoking and worshipping others besides Allah) has gone away from them.

(85) Indeed, We sent Nuh (Noah) to his people and he said: "O my people! worship Allah! You have no other Ilah (God) but Him. (La ilaha illallah: none has the right to be worshipped but Allah). Certainly, I fear for you the torment of a Great Day!"

(86) And to 'Ad (people, We sent) their brother Hud. He said: "O my people! worship Allah! You have no other Ilah (God) but Him. (La ilaha illallah: none has the right to be worshipped but Allah). Will you not fear (Allah)?"

(87) They said: "You have come to us that we should worship Allah Alone and forsake that which our fathers used to worship. So bring us that wherewith you have threatened us if you are of the truthful."

(88) And to Thamud (people, We sent) their brother Salih. He said: "O my people! worship Allah! You have no other Ilah (God) but Him. (La ilaha illallah: none has the right to be worshipped but Allah). Indeed there has come to you a clear sign (the miracle of the coming out of a huge she-camel from the midst of a rock) from your Lord. This she-camel of Allah is a sign unto you; so you leave her to graze in Allah's earth, and touch her not with harm, lest a painful torment should seize you.

(89) And to (the people of) Madyan (Midian), (We sent) their brother Shu'aib. He said: "O my people! worship Allah! You have no other Ilah (God) but Him. [La ilaha illallah (none has the right to be worshipped but Allah)]." Verily, a clear proof (sign) from your Lord has come unto you; so give full measure and full weight and wrong not men in their things, and do not do mischief on the earth after it has been set in order, that will be better for you, if you are believers.

(90) And We brought the Children of Israel (with safety) across the sea, and they came upon a people devoted to some of their idols (in worship). They said: "O Musa (Moses)! Make for us an ilah (a god) as they have alihah (gods)." He said: "Verily, you are a people who know not (the Majesty and Greatness of Allah and what is obligatory upon you, i.e. to worship none but Allah Alone, the One and the Only God of all that exists)."
