The word(s) "thought" appears 39 time(s) in 37 verse(s) in Quran in Muhammad Pickthal translation.

(21) Is it not a guidance for them (to know) how many a generation We destroyed before them, amid whose dwellings they walk? Lo! therein verily are signs for men of thought.

(22) Whoso is wont to think (through envy) that Allah will not give him (Muhammad) victory in the world and the Hereafter (and is enraged at the thought of his victory), let him stretch a rope up to the roof (of his dwelling), and let him hang himself. Then let him see whether his strategy dispelleth that whereat he rageth!.

(23) Say: Have ye thought, if Allah made night everlasting for you till the Day of Resurrection, who is a god beside Allah who could bring you light? Will ye not then hear?

(24) Say: Have ye thought, if Allah made day everlasting for you till the Day of Resurrection, who is a god beside Allah who could bring you night wherein ye rest? Will ye not then see?

(25) When they came upon you from above you and from below you, and when eyes grew wild and hearts reached to the throats, and ye were imagining vain thoughts concerning Allah.

(26) Lo! We purified them with a pure thought, remembrance of the Home (of the Hereafter).

(27) Allah receiveth (men's) souls at the time of their death, and that (soul) which dieth not (yet) in its sleep. He keepeth that (soul) for which He hath ordained death and dismisseth the rest till an appointed term. Lo! herein verily are portents for people who take thought.

(28) That, your thought which ye did think about your Lord, hath ruined you; and ye find yourselves (this day) among the lost.

(29) Or deem they that We cannot hear their secret thoughts and private confidences? Nay, but Our envoys, present with them, do record.

(30) Say (unto them, O Muhammad): Have ye thought on all that ye invoke beside Allah? Show me what they have created of the earth. Or have they any portion in the heavens? Bring me a scripture before this (Scripture), or some vestige of knowledge (in support of what ye say), if ye are truthful.
