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

(61) The Prophet is closer to the believers than their ownselves, and his wives are their (believers') mothers (as regards respect and marriage). And blood relations among each other have closer personal ties in the Decree of Allah (regarding inheritance) than (the brotherhood of) the believers and the Muhajirun (emigrants from Makkah), except that you do kindness to those brothers (when the Prophet صلى الله عليه وسلم joined them in brotherhood ties). This has been written in the (Allah's Book of Divine) Decrees - (Al-Lauh Al-Mahfuz)."

(62) O Prophet (Muhammad صلى الله عليه وسلم)! Verily, We have made lawful to you your wives, to whom you have paid their Mahr (bridal-money given by the husband to his wife at the time of marriage), and those (slaves) whom your right hand possesses - whom Allah has given to you, and the daughters of your 'Amm (paternal uncles) and the daughters of your 'Ammat (paternal aunts) and the daughters of your Khal (maternal uncles) and the daughters of your Khalat (maternal aunts) who migrated (from Makkah) with you, and a believing woman if she offers herself to the Prophet, and the Prophet wishes to marry her - a privilege for you only, not for the (rest of) the believers. Indeed We know what We have enjoined upon them about their wives and those (slaves) whom their right hands possess, in order that there should be no difficulty on you. And Allah is Ever Oft-Forgiving, Most Merciful.

(63) Say (O Muhammad صلى الله عليه وسلم to polytheists and pagans): "Show me those whom you have joined with Him as partners. Nay (there are not at all any partners with Him)! But He is Allah (Alone), the All-Mighty, the All-Wise."

(64) They will say: "It was you who used to come to us from the right side [i.e. from the right side of one of us and beautify for us every evil, enjoin on us polytheism, and stop us from the truth i.e. Islamic Monotheism and from every good deed]."

(65) And indeed it has been revealed to you (O Muhammad صلى الله عليه وسلم), as it was to those (Allah's Messengers) before you: "If you join others in worship with Allah, (then) surely (all) your deeds will be in vain, and you will certainly be among the losers."

(66) (It will be said): "This is because, when Allah Alone was invoked (in worship) you disbelieved (denied), but when partners were joined to Him, you believed! So the judgement is only with Allah, the Most High, the Most Great! "

(67) "You invite me to disbelieve in Allah (and in His Oneness), and to join partners in worship with Him of which I have no knowledge; and I invite you to the All-Mighty, the Oft-Forgiving!

(68) Then it will be said to them: "Where are (all) those whom you used to join in worship as partners

(69) And (remember) the Day that the enemies of Allah will be gathered to the Fire, then they will be driven [(to the Fire), former ones being withheld till their later ones will join them].

(70) And We have enjoined on man to be dutiful and kind to his parents. His mother bears him with hardship. And she brings him forth with hardship, and the bearing of him, and the weaning of him is thirty months, till when he attains full strength and reaches forty years, he says: "My Lord! Grant me the power and ability that I may be grateful for Your Favour which You have bestowed upon me and upon my parents, and that I may do righteous good deeds, such as please You, and make my offspring good. Truly, I have turned to You in repentance, and truly, I am one of the Muslims (submitting to Your Will)."
