The word(s) "wherewith" appears 21 time(s) in 15 verse(s) in Quran in Mohsin Khan translation.

(1) And whoever of you have not the means wherewith to wed free, believing women, they may wed believing girls from among those (slaves) whom your right hands possess, and Allah has full knowledge about your Faith; you are one from another. Wed them with the permission of their own folk (guardians, Auliya' or masters) and give them their Mahr according to what is reasonable; they (the above said captive and slave-girls) should be chaste, not committing illegal sex, nor taking boy-friends. And after they have been taken in wedlock, if they commit illegal sexual intercourse, their punishment is half that for free (unmarried) women. This is for him among you who is afraid of being harmed in his religion or in his body; but it is better for you that you practise self-restraint, and Allah is Oft-Forgiving, Most Merciful.

(2) wherewith Allah guides all those who seek His Good Pleasure to ways of peace, and He brings them out of darkness by His Will unto light and guides them to the Straight Way (Islamic Monotheism).

(3) They said: "You have come to us that we should worship Allah Alone and forsake that which our fathers used to worship. So bring us that wherewith you have threatened us if you are of the truthful."

(4) And surely, We have created many of the jinn and mankind for Hell. They have hearts wherewith they understand not, and they have eyes wherewith they see not, and they have ears wherewith they hear not (the truth). They are like cattle, nay even more astray; those! They are the heedless ones.

(5) Have they feet wherewith they walk? Or have they hands wherewith they hold? Or have they eyes wherewith they see? Or have they ears wherewith they hear? Say (O Muhammad صلى الله عليه وسلم): "Call your (so-called) partners (of Allah) and then plot against me, and give me no respite!

(6) He said: "This is my stick, whereon I lean, and wherewith I beat down branches for my sheep, and wherein I find other uses."

(7) (Saying) eat of the Tayyibat (good lawful things) wherewith We have provided you, and commit no transgression or oppression therein, lest My Anger should justly descend on you. And he on whom My Anger descends, he is indeed perished. [Tafsir At-Tabari]

(8) Have they not travelled through the land, and have they hearts wherewith to understand and ears wherewith to hear? Verily, it is not the eyes that grow blind, but it is the hearts which are in the breasts that grow blind.

(9) And if all the trees on the earth were pens and the sea (were ink wherewith to write), with seven seas behind it to add to its (supply), yet the Words of Allah would not be exhausted. Verily, Allah is All-Mighty, All-Wise.

(10) And a believing man of Fir'aun's (Pharaoh) family, who hid his faith said: "Would you kill a man because he says: My Lord is Allah, and he has come to you with clear signs (proofs) from your Lord? And if he is a liar, upon him will be (the sin of) his lie; but if he is telling the truth, then some of that (calamity) wherewith he threatens you will befall on you." Verily, Allah guides not one who is a Musrif (a polytheist, or a murderer who shed blood without a right, or those who commit great sins, oppressor, transgressor), a liar!
