The word(s) "forsake" appears 18 time(s) in 17 verse(s) in Quran in Muhammad Pickthal translation.

(1) And who forsaketh the religion of Abraham save him who befooleth himself? Verily We chose him in the world, and lo! in the Hereafter he is among the righteous.

(2) They long that ye should disbelieve even as they disbelieve, that ye may be upon a level (with them). So choose not friends from them till they forsake their homes in the way of Allah; if they turn back (to enmity) then take them and kill them wherever ye find them, and choose no friend nor helper from among them,

(3) Whoso migrateth for the cause of Allah will find much refuge and abundance in the earth, and whoso forsaketh his home, a fugitive unto Allah and His messenger, and death overtaketh him, his reward is then incumbent on Allah. Allah is ever Forgiving, Merciful.

(4) And forsake those who take their religion for a pastime and a jest, and whom the life of the world beguileth. Remind (mankind) hereby lest a soul be destroyed by what it earneth. It hath beside Allah no protecting ally nor intercessor, and though it offer every compensation it will not be accepted from it. Those are they who perish by their own deserts. For them is drink of boiling water and a painful doom, because they disbelieved.

(5) forsake the outwardness of sin and the inwardness thereof. Lo! those who garner sin will be awarded that which they have earned.

(6) They said: Hast come unto us that we should serve Allah alone, and forsake what our fathers worshipped? Then bring upon us that wherewith thou threatenest us if thou art of the truthful!

(7) A likely thing, that thou wouldst forsake aught of that which hath been revealed unto thee, and that thy breast should be straitened for it, because they say: Why hath not a treasure been sent down for him, or an angel come with him? Thou art but a warner, and Allah is in charge of all things.

(8) They said: O Hud! Thou hast brought us no clear proof and we are not going to forsake our gods on thy (mere) saying, and we are not believers in thee.

(9) (It was said) O Abraham! forsake this! Lo! thy Lord's commandment hath gone forth, and lo! there cometh unto them a doom which cannot be repelled.

(10) They said: O Shu'eyb! Doth thy way of prayer command thee that we should forsake that which our fathers (used to) worship, or that we (should leave off) doing what we will with our own property. Lo! thou art the mild, the guide to right behaviour.
