The word(s) "think" appears 88 time(s) in 85 verse(s) in Quran in Mohsin Khan translation.

(51) They think that Al-Ahzab (the Confederates) have not yet withdrawn; and if Al-Ahzab (the Confederates) should come (again), they would wish they were in the deserts (wandering) among the bedouins, seeking news about you (from a far place); and if they (happen) to be among you, they would not fight but little.

(52) Say (O Muhammad صلى الله عليه وسلم): "Tell me or inform me (what) do you think about your (so-called) partner-gods to whom you call upon besides Allah? Show me, what they have created of the earth. Or have they any share in the heavens? Or have We given them a Book, so that they act on clear proof therefrom? Nay, the Zalimun (polytheists and wrong-doers) promise one another nothing but delusions."

(53) "Then what think you about the Lord of the 'Alamin (mankind, jinn, and all that exists)?"

(54) And, when he (his son) was old enough to walk with him, he said: "O my son! I have seen in a dream that I am slaughtering you (offering you in sacrifice to Allah). So look what you think!" He said: "O my father! Do that which you are commanded, Insha' Allah (if Allah wills), you shall find me of As-Sabirun (the patient)."

(55) It is Allah Who takes away the souls at the time of their death, and those that die not during their sleep. He keeps those (souls) for which He has ordained death and sends the rest for a term appointed. Verily, in this are signs for a people who think deeply.

(56) "The ways of the heavens, and I may look upon the Ilah (God) of Musa (Moses): But verily, I think him to be a liar." Thus it was made fair-seeming, in Fir'aun's (Pharaoh) eyes, the evil of his deeds, and he was hindered from the (Right) Path; and the plot of Fir'aun (Pharaoh) led to nothing but loss and destruction (for him).

(57) And truly, if We give him a taste of mercy from Us, after some adversity (severe poverty or disease, etc.) has touched him, he is sure to say: "This is due to my (merit); I think not that the Hour will be established. But if I am brought back to my Lord, surely, there will be for me the best (wealth) with Him. Then, We verily, will show to the disbelievers what they have done, and We shall make them taste a severe torment.

(58) And verily, they (Satans / devils) hinder them from the Path (of Allah), but they think that they are guided aright!

(59) Or do they think that We hear not their secrets and their private counsel? (Yes We do) and Our messengers (appointed angels in charge of mankind) are by them, to record.

(60) And has subjected to you all that is in the heavens and all that is in the earth; it is all as a favour and kindness from Him. Verily, in it are signs for a people who think deeply.
