The word(s) "think" appears 59 time(s) in 58 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) Or do they who work evil think that they will escape Us? Evil is it that they judge!

(32) And among men is he who says: We believe in Allah; but when he is persecuted in (the way of) Allah he thinks the persecution of men to be as the chastisement of Allah; and if there come assistance from your Lord, they would most certainly say: Surely we were with you. What! is not Allah the best knower of what is in the breasts of mankind.

(33) When they came upon you from above you and from below you, and when the eyes turned dull, and the hearts rose up to the throats, and you began to think diverse thoughts of Allah.

(34) They think the allies are not gone, and if the allies should come (again) they would fain be in the deserts with the desert Arabs asking for news about you, and if they were among you they would not fight save a little.

(35) The means of access to the heavens, then reach the god of Musa, and I surely think him to be a liar. And thus the evil of his deed was made fairseeming to Firon, and he was turned away from the way; and the struggle of Firon was not (to end) in aught but destruction.

(36) And if We make him taste mercy from Us after distress that has touched him, he would most certainly say: This is of me, and I do not think the hour will come to pass, and if I am sent back to my Lord, I shall have with Him sure good; but We will most certainly inform those who disbelieved of what they did, and We will most certainly make them taste of hard chastisement.

(37) And most surely they turn them away from the path, and they think that they are guided aright:

(38) Or do they think that We do not hear what they conceal and their secret discourses? Aye! and Our apostles with them write down.

(39) Nay! do those who have wrought evil deeds think that We will make them like those who believe and do good-- that their life and their death shall be equal? Evil it is that they judge.

(40) And when it was said, Surely the promise of Allah is true and as for the hour, there is no doubt about it, you said: We do not know what the hour is; we do not think (that it will come to pass) save a passing thought, and we are not at all sure.
