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

(51) And (remember) Zakariya, when he cried to his Lord: "O my Lord! leave me not without offspring, though thou art the best of inheritors."

(52) Behold, ye received it on your tongues, and said out of your mouths things of which ye had no knowledge; and ye thought it to be a light matter, while it was most serious in the sight of Allah.

(53) Allah is the Light of the heavens and the earth. The Parable of His Light is as if there were a Niche and within it a Lamp: the Lamp enclosed in Glass: the glass as it were a brilliant star: Lit from a blessed Tree, an Olive, neither of the east nor of the west, whose oil is well-nigh luminous, though fire scarce touched it: Light upon Light! Allah doth guide whom He will to His Light: Allah doth set forth Parables for men: and Allah doth know all things.

(54) And they rejected those Signs in iniquity and arrogance, though their souls were convinced thereof: so see what was the end of those who acted corruptly!

(55) She was asked to enter the lofty Palace: but when she saw it, she thought it was a lake of water, and she (tucked up her skirts), uncovering her legs. He said: "This is but a palace paved smooth with slabs of glass." She said: "O my Lord! I have indeed wronged my soul: I do (now) submit (in Islam), with Solomon, to the Lord of the Worlds."

(56) (We also sent) Lut (as a messenger): behold, He said to his people, "Do ye do what is shameful though ye see (its iniquity)?

(57) Until, when they come (before the Judgment-seat), (Allah) will say: "Did ye reject My Signs, though ye comprehended them not in knowledge, or what was it ye did?"

(58) And he was arrogant and insolent in the land, beyond reason,- He and his hosts: they thought that they would not have to return to Us!

(59) (Remember also) the 'Ad and the Thamud (people): clearly will appear to you from (the traces) of their buildings (their fate): the Evil One made their deeds alluring to them, and kept them back from the Path, though they were gifted with intelligence and skill.

(60) Even though, before they received (the rain) - just before this - they were dumb with despair!
