The word(s) "rivals" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Who has made the earth your couch, and the heavens your canopy; and sent down rain from the heavens; and brought forth therewith Fruits for your sustenance; then set not up rivals unto Allah when ye know (the truth).

(2) When some trouble toucheth man, he crieth unto his Lord, turning to Him in repentance: but when He bestoweth a favour upon him as from Himself, (man) doth forget what he cried and prayed for before, and he doth set up rivals unto Allah, thus misleading others from Allah's Path. Say, "Enjoy thy blasphemy for a little while: verily thou art (one) of the Companions of the Fire!"
