The word(s) "strong" appears 35 time(s) in 34 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) And Allah turned back the unbelievers in their rage; they did not obtain any advantage, and Allah sufficed the believers in fighting; and Allah is strong, Mighty.

(22) And they swore by Allah with the strongest of their oaths that if there came to them a warner they would be better guided than any of the nations; but when there came to them a warner it increased them in naught but aversion.

(23) Have they not travelled in the land and seen how was the end of those before them while they were stronger than these in power? And Allah is not such that any thing in the heavens or in the earth should escape Him; surely He is Knowing, Powerful.

(24) Then ask them whether they are stronger in creation or those (others) whom We have created. Surely We created them of firm clay.

(25) That was because there came to them their apostles with clear arguments, but they rejected (them), therefore Allah destroyed them; surely He is strong, Severe in retribution.

(26) Allah is Benignant to His servants; He gives sustenance to whom He pleases, and He is the strong, the Mighty.

(27) Then We destroyed those who were stronger than these in prowess, and the case of the ancients has gone before,

(28) Surely Allah is the Bestower of sustenance, the Lord of Power, the strong.

(29) Certainly We sent Our apostles with clear arguments, and sent down with them the Book and the balance that men may conduct themselves with equity; and We have made the iron, wherein is great violence and advantages to men, and that Allah may know who helps Him and His apostles in the secret; surely Allah is strong, Mighty.

(30) Allah has written down: I will most certainly prevail, I and My apostles; surely Allah is strong, Mighty.
