The word(s) "join" appears 84 time(s) in 80 verse(s) in Quran in Mohsin Khan translation.

(11) They rejoice in what Allah has bestowed upon them of His Bounty and rejoice for the sake of those who have not yet joined them, but are left behind (not yet martyred) that on them no fear shall come, nor shall they grieve.

(12) Worship Allah and join none with Him (in worship); and do good to parents, kinsfolk, orphans, Al-Masakin (the poor), the neighbour who is near of kin, the neighbour who is a stranger, the companion by your side, the wayfarer (you meet), and those (slaves) whom your right hands possess. Verily, Allah does not like such as are proud and boastful.

(13) Those who are miserly and enjoin miserliness on other men and hide what Allah has bestowed upon them of His Bounties. And We have prepared for the disbelievers a disgraceful torment.

(14) Except those who join a group, between you and whom there is a treaty (of peace), or those who approach you with their breasts restraining from fighting you as well as fighting their own people. Had Allah willed, indeed He would have given them power over you, and they would have fought you. So if they withdraw from you, and fight not against you, and offer you peace, then Allah has opened no way for you against them.

(15) When you have finished As-Salat (the congregational prayer), remember Allah standing, sitting down, and (lying down) on your sides, but when you are free from danger, perform As-Salat (Iqamat-as-Salat). Verily, As-Salat (the prayer) is enjoined on the believers at fixed hours.

(16) And (as for) the male thief and the female thief, cut off (from the wrist joint) their (right) hands as a recompense for that which they committed, a punishment by way of example from Allah. And Allah is All-Powerful, All-Wise.

(17) O you who believe! Take care of your ownselves . If you follow the (right) guidance [and enjoin what is right (Islamic Monotheism and all that Islam orders one to do) and forbid what is wrong (polytheism, disbelief and all that Islam has forbidden)] no hurt can come to you from those who are in error. The return of you all is to Allah, then He will inform you about (all) that which you used to do.

(18) Say (O Muhammad صلى الله عليه وسلم): "What thing is the most great in witness?" Say: "Allah (the Most Great!) is Witness between me and you; this Qur'an has been revealed to me that I may therewith warn you and whomsoever it may reach. Can you verily bear witness that besides Allah there are other alihah (gods)?" Say "I bear no (such) witness!" Say: "But in truth He (Allah) is the only one Ilah (God). And truly I am innocent of what you join in worship with Him."

(19) And on the Day when We shall gather them all together, then We shall say to those who joined partners (in worship with Us): "Where are your partners (false deities) whom you used to assert (as partners in worship with Allah)?"

(20) There will then be (left) no Fitnah (excuses or statements or arguments) for them but to say: "By Allah, our Lord, we were not those who joined others in worship with Allah."
