The word(s) "co-equal" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) Lord of the heavens and the earth, and all that is between them, so worship Him (Alone) and be constant and patient in His worship. Do you know of any who is similar to Him? (of course none is similar or co-equal or comparable to Him, and He has none as partner with Him). [There is nothing like Him and He is the All-Hearer, the All-Seer].

(2) "And there is none co-equal or comparable unto Him."
