The word(s) "so-called" appears 20 time(s) in 18 verse(s) in Quran in Mohsin Khan translation.

(11) And (remember) the Day when He will call to them and say: "Where are My (so-called) partners whom you used to assert?"

(12) And it will be said (to them): "Call upon your (so-called) partners (of Allah)", and they will call upon them, but they will give no answer to them, and they will see the torment. (They will then wish) if only they had been guided!

(13) And (remember) the Day when He (your Lord - Allah) will call to them (those who worshipped others along with Allah), and will say: "Where are My (so-called) partners, whom you used to assert?"

(14) No intercessors will they have from those whom they made equal with Allah (partners i.e. their so-called associate gods), and they will (themselves) reject and deny their partners.

(15) Allah is He Who created you, then provided food for you, then will cause you to die, then (again) He will give you life (on the Day of Resurrection). Is there any of your (so-called) partners (of Allah) that do anything of that? Glory be to Him! And Exalted be He above all that (evil) they associate (with Him).

(16) Say (O Muhammad صلى الله عليه وسلم): "Tell me or inform me (what) do you think about your (so-called) partner-gods to whom you call upon besides Allah? Show me, what they have created of the earth. Or have they any share in the heavens? Or have We given them a Book, so that they act on clear proof therefrom? Nay, the Zalimun (polytheists and wrong-doers) promise one another nothing but delusions."

(17) And they have taken besides Allah alihah (gods), hoping that they might be helped (by those so-called gods).

(18) To Him (Alone) is referred the knowledge of the Hour. No fruit comes out of its sheath, nor does a female conceive nor brings forth (young), except by His Knowledge. And on the Day when He will call unto them (polytheists) (saying): "Where are My (so-called) partners (whom you did invent)?" They will say: "We inform You that none of us bears witness to it (that they are Your partners)!"
