The word(s) "partner" appears 76 time(s) in 64 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) Say: "Show me those whom ye have joined with Him as partners: by no means (can ye). Nay, He is Allah, the Exalted in Power, the Wise."

(52) If ye invoke them, they will not listen to your call, and if they were to listen, they cannot answer your (prayer). On the Day of Judgment they will reject your "partnership". and none, (O man!) can tell thee (the Truth) like the One Who is acquainted with all things.

(53) Say: "Have ye seen (these) 'partners' of yours whom ye call upon besides Allah? Show Me what it is they have created in the (wide) earth. Or have they a share in the heavens? Or have We given them a Book from which they (can derive) clear (evidence)?- Nay, the wrong-doers promise each other nothing but delusions.

(54) (David) said: "He has undoubtedly wronged thee in demanding thy (single) ewe to be added to his (flock of) ewes: truly many are the partners (in business) who wrong each other: Not so do those who believe and work deeds of righteousness, and how few are they?"... and David gathered that We had tried him: he asked forgiveness of his Lord, fell down, bowing (in prostration), and turned (to Allah in repentance).

(55) Allah puts forth a Parable a man belonging to many partners at variance with each other, and a man belonging entirely to one master: are those two equal in comparison? Praise be to Allah! but most of them have no knowledge.

(56) No just estimate have they made of Allah, such as is due to Him: On the Day of Judgment the whole of the earth will be but His handful, and the heavens will be rolled up in His right hand: Glory to Him! High is He above the partners they attribute to Him!

(57) (The answer will be:) "This is because, when Allah was invoked as the Only (object of worship), ye did reject Faith, but when partners were joined to Him, ye believed! the Command is with Allah, Most High, Most Great!"

(58) "Ye do call upon me to blaspheme against Allah, and to join with Him partners of whom I have no knowledge; and I call you to the Exalted in Power, Who forgives again and again!"

(59) But when they saw Our Punishment, they said: "We believe in Allah,- the one Allah - and we reject the partners we used to join with Him."

(60) To Him is referred the Knowledge of the Hour (of Judgment: He knows all): No date-fruit comes out of its sheath, nor does a female conceive (within her womb) nor bring forth the Day that (Allah) will propound to them the (question), "Where are the partners (ye attributed to Me?" They will say, "We do assure thee not one of us can bear witness!"
