The word(s) "though" appears 91 time(s) in 89 verse(s) in Quran in Abdullah Yusuf Ali translation.

(61) Behold! they came on you from above you and from below you, and behold, the eyes became dim and the hearts gaped up to the throats, and ye imagined various (vain) thoughts about Allah!

(62) Behold! A party among them said: "Ye men of Yathrib! ye cannot stand (the attack)! therefore go back!" And a band of them ask for leave of the Prophet, saying, "Truly our houses are bare and exposed," though they were not exposed they intended nothing but to run away.

(63) It is not lawful for thee (to marry more) women after this, nor to change them for (other) wives, even though their beauty attract thee, except any thy right hand should possess (as handmaidens): and Allah doth watch over all things.

(64) Nor can a bearer of burdens bear another's burdens if one heavily laden should call another to (bear) his load. Not the least portion of it can be carried (by the other). Even though he be nearly related. Thou canst but admonish such as fear their Lord unseen and establish regular Prayer. And whoever purifies himself does so for the benefit of his own soul; and the destination (of all) is to Allah.

(65) Do they not travel through the earth, and see what was the End of those before them,- though they were superior to them in strength? Nor is Allah to be frustrated by anything whatever in the heavens or on earth: for He is All-Knowing. All-Powerful.

(66) Not without purpose did We create heaven and earth and all between! that were the thought of Unbelievers! but woe to the Unbelievers because of the Fire (of Hell)!

(67) Call ye, then, upon Allah with sincere devotion to Him, even though the Unbelievers may detest it.

(68) It is He Who has created you from dust then from a sperm-drop, then from a leech-like clot; then does he get you out (into the light) as a child: then lets you (grow and) reach your age of full strength; then lets you become old,- though of you there are some who die before;- and lets you reach a Term appointed; in order that ye may learn wisdom.

(69) "But this thought of yours which ye did entertain concerning your Lord, hath brought you to destruction, and (now) have ye become of those utterly lost!"

(70) But (there is one) who says to his parents, "Fie on you! Do ye hold out the promise to me that I shall be raised up, even though generations have passed before me (without rising again)?" And they two seek Allah's aid, (and rebuke the son): "Woe to thee! Have faith! for the promise of Allah is true." But he says, "This is nothing but tales of the ancients!"
