The word(s) "authority" appears 38 time(s) in 38 verse(s) in Quran in Mohsin Khan translation.

(31) Those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority that has come to them, it is greatly hateful and disgusting to Allah and to those who believe. Thus does Allah seal up the heart of every arrogant, tyrant. (So they cannot guide themselves to the Right Path).

(32) Verily those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad صلى الله عليه وسلم) as a Messenger of Allah and to obey you] . They will never have it (i.e. Prophethood which Allah has bestowed upon you). So seek refuge in Allah (O Muhammad صلى الله عليه وسلم from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.

(33) "And exalt not yourselves against Allah. Truly, I have come to you with a manifest authority.

(34) Would you then, if you were given the authority, do mischief in the land, and sever your ties of kinship?

(35) And in Musa (Moses) (too, there is a sign), when We sent him to Fir'aun (Pharaoh) with a manifest authority.

(36) Or are with them the treasures of your Lord? Or are they the tyrants with the authority to do as they like?

(37) They are but names which you have named - you and your fathers - for which Allah has sent down no authority. They follow but a guess and that which they themselves desire, whereas there has surely come to them the Guidance from their Lord!

(38) O assembly of jinn and men! If you have power to pass beyond the zones of the heavens and the earth, then pass beyond (them)! But you will never be able to pass them, except with authority (from Allah)!
