The word(s) "establish" appears 55 time(s) in 54 verse(s) in Quran in Muhammad Pickthal translation.

(31) And We made them chiefs who guide by Our command, and We inspired in them the doing of good deeds and the right establishment of worship and the giving of alms, and they were worshippers of Us (alone).

(32) Whose hearts fear when Allah is mentioned, and the patient of whatever may befall them, and those who establish worship and who spend of that We have bestowed on them.

(33) Those who, if We give them power in the land, establish worship and pay the poor-due and enjoin kindness and forbid iniquity. And Allah's is the sequel of events.

(34) Never sent We a messenger or a prophet before thee but when He recited (the message) Satan proposed (opposition) in respect of that which he recited thereof. But Allah abolisheth that which Satan proposeth. Then Allah establisheth His revelations. Allah is Knower, Wise;

(35) And strive for Allah with the endeavour which is His right. He hath chosen you and hath not laid upon you in religion any hardship; the faith of your father Abraham (is yours). He hath named you Muslims of old time and in this (Scripture), that the messenger may be a witness against you, and that ye may be witnesses against mankind. So establish worship, pay the poor-due, and hold fast to Allah. He is your Protecting friend. A blessed Patron and a blessed Helper!

(36) Allah hath promised such of you as believe and do good work that He will surely make them to succeed (the present rulers) in the earth even as He caused those who were before them to succeed (others); and that He will surely establish for them their religion which He hath approved for them, and will give them in exchange safety after their fear. They serve Me. They ascribe no thing as partner unto Me. Those who disbelieve henceforth, they are the miscreants.

(37) establish worship and pay the poor-due and obey the messenger, that haply ye may find mercy.

(38) Who establish worship and pay the poor-due and are sure of the Hereafter.

(39) And to establish them in the earth, and to show Pharaoh and Haman and their hosts that which they feared from them.

(40) And they say: If we were to follow the Guidance with thee we should be torn out of our land. Have We not established for them a sure sanctuary, whereunto the produce of all things is brought (in trade), a provision from Our presence? But most of them know not.
