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

(51) Fear ye to offer alms before your conference? Then, when ye do it not and Allah hath forgiven you, establish worship and pay the poor-due and obey Allah and His messenger. And Allah is Aware of what ye do.

(52) Lo! thy Lord knoweth how thou keepest vigil sometimes nearly two-thirds of the night, or (sometimes) half or a third thereof, as do a party of those with thee. Allah measureth the night and the day. He knoweth that ye count it not, and turneth unto you in mercy. Recite, then, of the Qur'an that which is easy for you. He knoweth that there are sick folk among you, while others travel in the land in search of Allah's bounty, and others (still) are fighting for the cause of Allah. So recite of it that which is easy (for you), and establish worship and pay the poor-due, and (so) lend unto Allah a goodly loan. Whatsoever good ye send before you for your souls, ye will find it with Allah, better and greater in the recompense. And seek forgiveness of Allah. Lo! Allah is Forgiving, Merciful.

(53) Mighty, established in the presence of the Lord of the Throne,

(54) And they are ordered naught else than to serve Allah, keeping religion pure for Him, as men by nature upright, and to establish worship and to pay the poor-due. That is true religion.
