The word(s) "whereof" appears 13 time(s) in 13 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) "O my two companions of the prison! As to one of you, he will pour out the wine for his lord to drink: as for the other, he will hang from the cross, and the birds will eat from off his head. (so) hath been decreed that matter whereof ye twain do enquire"...

(2) He rules (all) affairs from the heavens to the earth: in the end will (all affairs) go up to Him, on a Day, the space whereof will be (as) a thousand years of your reckoning.

(3) A Book, whereof the verses are explained in detail;- a Qur'an in Arabic, for people who understand;-

(4) That is (the Bounty) whereof Allah gives Glad Tidings to His Servants who believe and do righteous deeds. Say: "No reward do I ask of you for this except the love of those near of kin." And if any one earns any good, We shall give him an increase of good in respect thereof: for Allah is Oft-Forgiving, Most Ready to appreciate (service).

(5) We created not the heavens and the earth and all between them but for just ends, and for a Term Appointed: But those who reject Faith turn away from that whereof they are warned.

(6) Or do they say, "He has forged it"? Say: "Had I forged it, then can ye obtain no single (blessing) for me from Allah. He knows best of that whereof ye talk (so glibly)! Enough is He for a witness between me and you! And he is Oft-Forgiving, Most Merciful."

(7) And the Trumpet shall be blown: that will be the Day whereof Warning (had been given).

(8) Believe in Allah and His messenger, and spend (in charity) out of the (substance) whereof He has made you heirs. For, those of you who believe and spend (in charity),- for them is a great Reward.

(9) Be ye foremost (in seeking) Forgiveness from your Lord, and a Garden (of Bliss), the width whereof is as the width of heaven and earth, prepared for those who believe in Allah and His messengers: that is the Grace of Allah, which He bestows on whom he pleases: and Allah is the Lord of Grace abounding.

(10) The Fruits whereof (will hang in bunches) low and near.
