The word(s) "mighty" appears 102 time(s) in 101 verse(s) in Quran in Mohsin Khan translation.

(81) And remember (Hud) the brother of 'Ad, when he warned his people in Al-Ahqaf (the curved sand-hills in the southern part of Arabian Peninsula). And surely, there have passed away warners before him and after him (saying): "Worship none but Allah; truly, I fear for you the torment of a mighty Day (i.e. the Day of Resurrection)."

(82) And abundant spoils that they will capture. And Allah is Ever All-mighty, All-Wise.

(83) Muhammad (صلى الله عليه وسلم) is the Messenger of Allah. And those who are with him are severe against disbelievers, and merciful among themselves. You see them bowing and falling down prostrate (in prayer), seeking Bounty from Allah and (His) Good Pleasure. The mark of them (i.e. of their Faith) is on their faces (foreheads) from the traces of prostration (during prayers). This is their description in the Taurat (Torah). But their description in the Injeel (Gospel) is like a (sown) seed which sends forth its shoot, then makes it strong, and becomes thick and it stands straight on its stem, delighting the sowers, that He may enrage the disbelievers with them. Allah has promised those among them who believe (i.e. all those who follow Islamic Monotheism, the religion of Prophet Muhammad صلى الله عليه وسلم till the Day of Resurrection) and do righteous good deeds, forgiveness and a mighty reward (i.e. Paradise).

(84) There they will have all that they desire - and We have more (for them, i.e. a glance at the All-mighty, All-Majestic جل جلاله).

(85) He has been taught (this Qur'an) by one mighty in power [Jibril (Gabriel)]

(86) (They) belied all Our Signs, so We seized them with a Seizure of the All-mighty, All-Capable (Omnipotent).

(87) Whatsoever is in the heavens and the earth glorifies Allah - and He is the All-mighty, All-Wise.

(88) Indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance (justice) that mankind may keep up justice. And We brought forth iron wherein is mighty power (in matters of war ), as well as many benefits for mankind, that Allah may test who it is that will help Him (His religion) and His Messengers in the unseen. Verily, Allah is All-Strong, All-mighty.

(89) Allah has decreed: "Verily, it is I and My Messengers who shall be the victorious." Verily, Allah is All-Powerful, All-mighty.

(90) Whatsoever is in the heavens and whatsoever is on the earth glorifies Allah. And He is the All-mighty, the All-Wise.
