The word(s) "whereof" appears 24 time(s) in 24 verse(s) in Quran in Mohsin Khan translation.

(11) "Or (why) has not a treasure been granted to him, or why has he not a garden whereof he may eat?" And the Zalimun (polytheists and wrong-doers) say: "You follow none but a man bewitched."

(12) He manages and regulates (every) affair from the heavens to the earth; then it (affair) will go up to Him, in one Day, the space whereof is a thousand years of your reckoning (i.e. reckoning of our present world's time).

(13) A Book whereof the Verses are explained in detail - a Qur'an in Arabic for people who know.

(14) That is (the Paradise) whereof Allah gives glad tidings to His slaves who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds. Say (O Muhammad صلى الله عليه و سلم): "No reward do I ask of you for this except to be kind to me for my kinship with you." And whoever earns a good righteous deed, We shall give him an increase of good in respect thereof. Verily, Allah is Oft-Forgiving, Most Ready to appreciate (the deeds of those who are obedient to Him).

(15) "Verily, this is that whereof you used to doubt!"

(16) We created not the heavens and the earth and all that is between them except with truth, and for an appointed term. But those who disbelieve turn away from that whereof they are warned.

(17) And the Trumpet will be blown - that will be the Day whereof warning (had been given) (i.e. the Day of Resurrection).

(18) Believe in Allah and His Messenger (Muhammad صلى الله عليه وسلم), and spend of that whereof He has made you trustees. And such of you as believe and spend (in Allah's Way), theirs will be a great reward.

(19) Race with one another in hastening towards forgiveness from your Lord (Allah), and Paradise the width whereof is as the width of the heaven and the earth, prepared for those who believe in Allah and His Messengers. That is the Grace of Allah which He bestows on whom He is pleased with. And Allah is the Owner of Great Bounty.

(20) He it is Who drove out the disbelievers among the people of the Scripture (i.e. the Jews of the tribe of Banu An-Nadir) from their homes at the first gathering. You did not think that they would get out. And they thought that their fortresses would defend them from Allah! But Allah's (Torment) reached them from a place whereof they expected it not, and He cast terror into their hearts so that they destroyed their own dwellings with their own hands and the hands of the believers. Then take admonition, O you with eyes (to see).
