The word(s) "join" appears 48 time(s) in 46 verse(s) in Quran in Muhammad Pickthal translation.

(21) The hypocrites, both men and women, proceed one from another. They enjoin the wrong, and they forbid the right, and they withhold their hands (from spending for the cause of Allah). They forget Allah, so He hath forgotten them. Lo! the hypocrites, they are the transgressors.

(22) And the believers, men and women, are protecting friends one of another; they enjoin the right and forbid the wrong, and they establish worship and they pay the poor-due, and they obey Allah and His messenger. As for these, Allah will have mercy on them. Lo! Allah is Mighty, Wise.

(23) (Triumphant) are those who turn repentant (to Allah), those who serve (Him), those who praise (Him), those who fast, those who bow down, those who fall prostrate (in worship), those who enjoin the right and who forbid the wrong and those who keep the limits (ordained) of Allah - And give glad tidings to believers!

(24) I do not exculpate myself. Lo! the (human) soul enjoineth unto evil, save that whereon my Lord hath mercy. Lo! my Lord is Forgiving, Merciful.

(25) And when they entered in the manner which their father had enjoined, it would have naught availed them as against Allah; it was but a need of Jacob's soul which he thus satisfied; and lo! he was a lord of knowledge because We had taught him; but most of mankind know not.

(26) O my Lord! Thou hast given me (something) of sovereignty and hast taught me (something) of the interpretation of events - Creator of the heavens and the earth! Thou art my Protecting Guardian in the world and the Hereafter. Make me to die muslim (unto Thee), and join me to the righteous.

(27) Such as unite that which Allah hath commandeth should be joined, and fear their Lord, and dread a woeful reckoning;

(28) And those who break the covenant of Allah after ratifying it, and sever that which Allah hath commanded should be joined, and make mischief in the earth: theirs is the curse and theirs the ill abode.

(29) Strain not thine eyes toward that which We cause some wedded pairs among them to enjoin, and be not grieved on their account, and lower thy wing (in tenderness) for the believers.

(30) And Allah coineth a similitude: Two men, one of them dumb, having control of nothing, and he is a burden on his owner; whithersoever he directeth him to go, he bringeth no good. Is he equal with one who enjoineth justice and followeth a straight path (of conduct)?
