The word(s) "thereof" appears 166 time(s) in 142 verse(s) in Quran in Muhammad Pickthal translation.

(51) And We send the winds fertilising, and cause water to descend from the sky, and give it you to drink. It is not ye who are the holders of the store thereof.

(52) And Allah hath favoured some of you above others in provision. Now those who are more favoured will by no means hand over their provision to those (slaves) whom their right hands possess, so that they may be equal with them in respect thereof. Is it then the grace of Allah that they deny?

(53) Allah coineth a similitude: (on the one hand) a (mere) chattel slave, who hath control of nothing, and (on the other hand) one on whom we have bestowed a fair provision from Us, and he spendeth thereof secretly and openly. Are they equal? Praise be to Allah! But most of them know not.

(54) Whoso desireth that (life) which hasteneth away, We hasten for him therein what We will for whom We please. And afterward We have appointed for him hell; he will endure the heat thereof, condemned, rejected.

(55) And if We willed We could withdraw that which We have revealed unto thee, then wouldst thou find no guardian for thee against Us in respect thereof.

(56) Say: Verily, though mankind and the jinn should assemble to produce the like of this Qur'an, they could not produce the like thereof though they were helpers one of another.

(57) Lo! We have placed all that is on the earth as an ornament thereof that We may try them: which of them is best in conduct.

(58) And thou mightest have seen the sun when it rose move away from their cave to the right, and when it set go past them on the left, and they were in the cleft thereof. That was (one) of the portents of Allah. He whom Allah guideth, he indeed is led aright, and he whom He sendeth astray, for him thou wilt not find a guiding friend.

(59) And in like manner We awakened them that they might question one another. A speaker from among them said: How long have ye tarried? They said: We have tarried a day or some part of a day, (Others) said: Your Lord best knoweth what ye have tarried. Now send one of you with this your silver coin unto the city, and let him see what food is purest there and bring you a supply thereof. Let him be courteous and let no man know of you.

(60) Each of the gardens gave its fruit and withheld naught thereof. And We caused a river to gush forth therein.
