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

(41) Say: Show me those whom ye have joined unto Him as partners. Nay (ye dare not)! For He is Allah, the Mighty, the Wise.

(42) And if those who disbelieve join battle with you they will take to flight, and afterward they will find no protecting friend nor helper.

(43) And they who believe and whose seed follow them in faith, We cause their seed to join them (there), and We deprive them of nought of their (life's) work. Every man is a pledge for that which he hath earned.

(44) Who hoard and who enjoin upon the people avarice. And whosoever turneth away, still Allah is the Absolute, the Owner of Praise.

(45) Along with others of them who have not yet joined them. He is the Mighty, the Wise.

(46) Or enjoineth piety?
