The word(s) "strong" appears 52 time(s) in 50 verse(s) in Quran in Mohsin Khan translation.

(41) 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).

(42) And how many a generation We have destroyed before them who were stronger in power than they. And (when Our Torment came), they ran for a refuge in the land! Could they find any place of refuge (for them to save themselves from destruction)?

(43) Verily, Allah is the All-Provider, Owner of Power, the Most strong.

(44) 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.

(45) And they went in the morning with strong intention, thinking that they have power (to prevent the poor taking anything of the fruits therefrom).

(46) And I will grant them a respite. Verily, My Plan is strong.

(47) And they disobeyed their Lord's Messenger, so He seized them with a strong punishment.

(48) It is We Who created them, and We have made them of strong built. And when We will, We can replace them with others like them with a complete replacement.

(49) And We have built above you seven strong (heavens),

(50) Then they denied him and they killed it. So their Lord destroyed them because of their sin, and made them equal in destruction (i.e. all grades of people, rich and poor, strong and weak, etc.)!
