The word(s) "join" appears 89 time(s) in 83 verse(s) in Quran in Abdullah Yusuf Ali translation.

(31) One day shall We gather them all together. Then shall We say to those who joined gods (with Us): "To your place! ye and those ye joined as 'partners' We shall separate them, and their "Partners" shall say: "It was not us that ye worshipped!

(32) He said: "O my Lord! the prison is more to my liking than that to which they invite me: Unless Thou turn away their snare from me, I should (in my youthful folly) feel inclined towards them and join the ranks of the ignorant."

(33) And when they entered in the manner their father had enjoined, it did not profit them in the least against (the plan of) Allah: It was but a necessity of Jacob's soul, which he discharged. For he was, by our instruction, full of knowledge (and experience): but most men know not.

(34) Say thou: "This is my way: I do invite unto Allah,- on evidence clear as the seeing with one's eyes,- I and whoever follows me. Glory to Allah! and never will I join gods with Allah!"

(35) Those who join together those things which Allah hath commanded to be joined, hold their Lord in awe, and fear the terrible reckoning;

(36) But those who break the Covenant of Allah, after having plighted their word thereto, and cut asunder those things which Allah has commanded to be joined, and work mischief in the land;- on them is the curse; for them is the terrible home!

(37) Those to whom We have given the Book rejoice at what hath been revealed unto thee: but there are among the clans those who reject a part thereof. Say: "I am commanded to worship Allah, and not to join partners with Him. Unto Him do I call, and unto Him is my return."

(38) Therefore expound openly what thou art commanded, and turn away from those who join false gods with Allah.

(39) Yet, when He removes the distress from you, behold! some of you turn to other gods to join with their Lord-

(40) His authority is over those only, who take him as patron and who join partners with Allah.
