The word(s) "thereof" appears 20 time(s) in 18 verse(s) in Quran in Saheeh International translation.

(1) And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful.

(2) And it is not [possible] for one to die except by permission of Allah at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And we will reward the grateful.

(3) And leave what is apparent of sin and what is concealed thereof. Indeed, those who earn [blame for] sin will be recompensed for that which they used to commit.

(4) Whoever comes [on the Day of Judgement] with a good deed will have ten times the like thereof [to his credit], and whoever comes with an evil deed will not be recompensed except the like thereof; and they will not be wronged.

(5) And [had you been present], you would see the sun when it rose, inclining away from their cave on the right, and when it set, passing away from them on the left, while they were [laying] within an open space thereof. That was from the signs of Allah. He whom Allah guides is the [rightly] guided, but he whom He leaves astray - never will you find for him a protecting guide.

(6) Each of the two gardens produced its fruit and did not fall short thereof in anything. And We caused to gush forth within them a river.

(7) [Moses] said, "The knowledge thereof is with my Lord in a record. My Lord neither errs nor forgets."

(8) So We responded to him and removed what afflicted him of adversity. And We gave him [back] his family and the like thereof with them as mercy from Us and a reminder for the worshippers [of Allah].

(9) Indeed, those who came with falsehood are a group among you. Do not think it bad for you; rather it is good for you. For every person among them is what [punishment] he has earned from the sin, and he who took upon himself the greater portion thereof - for him is a great punishment.

(10) And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed.
