The word(s) "thoughts" appears 5 time(s) in 5 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Then after sorrow He sent down security upon you, a calm coming upon a party of you, and (there was) another party whom their own souls had rendered anxious; they entertained about Allah thoughts of ignorance quite unjustly, saying: We have no hand in the affair. Say: Surely the affair is wholly (in the hands) of Allah. They conceal within their souls what they would not reveal to you. They say: Had we any hand in the affair, we would not have been slain here. Say: Had you remained in your houses, those for whom slaughter was ordained would certainly have gone forth to the places where they would be slain, and that Allah might test what was in your breasts and that He might purge what was in your hearts; and Allah knows what is in the breasts.

(2) And He is Allah in the heavens and in the earth; He knows your secret (thoughts) and your open (words), and He knows what you earn.

(3) Do they not know that Allah knows their hidden thoughts and their secret counsels, and that Allah is the great Knower of the unseen things?

(4) 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.

(5) And (that) He may punish the hypocritical men and the hypocritical women, and the polytheistic men and the polytheistic women, the entertainers of evil thoughts about Allah. On them is the evil turn, and Allah is wroth with them and has cursed them and prepared hell for them, and evil is the resort.
