The word(s) "though" appears 144 time(s) in 137 verse(s) in Quran in Muhammad Pickthal translation.

(71) And thou wouldst have deemed them waking though they were asleep, and We caused them to turn over to the right and the left, and their dog stretching out his paws on the threshold. If thou hadst observed them closely thou hadst assuredly turned away from them in flight, and hadst been filled with awe of them.

(72) If only, when thou enteredst thy garden, thou hadst said: That which Allah willeth (will come to pass)! There is no strength save in Allah! though thou seest me as less than thee in wealth and children,

(73) And they are set before thy Lord in ranks (and it is said unto them): Now verily have ye come unto Us as We created you at the first. But ye thought that We had set no tryst for you.

(74) And who doth greater wrong than he who hath been reminded of the revelations of his Lord, yet turneth away from them and forgetteth what his hands send forward (to the Judgment)? Lo! on their hearts We have placed coverings so that they understand not, and in their ears a deafness. And though thou call them to the guidance, in that case they can never be led aright.

(75) And when Moses said unto his servant: I will not give up until I reach the point where the two rivers meet, though I march on for ages.

(76) Say: though the sea became ink for the Words of my Lord, verily the sea would be used up before the words of my Lord were exhausted, even though We brought the like thereof to help.

(77) And if thou speakest aloud, then lo! He knoweth the secret (thought) and (that which is yet) more hidden.

(78) Therefor, let not him turn thee aside from (the thought of) it who believeth not therein but followeth his own desire, lest thou perish.

(79) (Saying): Eat ye and feed your cattle. Lo! herein verily are portents for men of thought.

(80) He said: Nay, do ye throw! Then lo! their cords and their staves, by their magic, appeared to him as though they ran.
