The word(s) "well" appears 261 time(s) in 247 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) They (his dupes) will have their dwelling in Hell, and from it they will find no way of escape.

(42) But those who believe and do deeds of righteousness,- we shall soon admit them to gardens, with rivers flowing beneath,-to dwell therein for ever. Allah's promise is the truth, and whose word can be truer than Allah's?

(43) They ask thy instruction concerning the women say: Allah doth instruct you about them: And (remember) what hath been rehearsed unto you in the Book, concerning the orphans of women to whom ye give not the portions prescribed, and yet whom ye desire to marry, as also concerning the children who are weak and oppressed: that ye stand firm for justice to orphans. There is not a good deed which ye do, but Allah is well-acquainted therewith.

(44) If a wife fears cruelty or desertion on her husband's part, there is no blame on them if they arrange an amicable settlement between themselves; and such settlement is best; even though men's souls are swayed by greed. But if ye do good and practise self-restraint, Allah is well-acquainted with all that ye do.

(45) O ye who believe! stand out firmly for justice, as witnesses to Allah, even as against yourselves, or your parents, or your kin, and whether it be (against) rich or poor: for Allah can best protect both. Follow not the lusts (of your hearts), lest ye swerve, and if ye distort (justice) or decline to do justice, verily Allah is well-acquainted with all that ye do.

(46) But those among them who are well-grounded in knowledge, and the believers, believe in what hath been revealed to thee and what was revealed before thee: And (especially) those who establish regular prayer and practise regular charity and believe in Allah and in the Last Day: To them shall We soon give a great reward.

(47) Messengers who gave good news as well as warning, that mankind, after (the coming) of the messengers, should have no plea against Allah: For Allah is Exalted in Power, Wise.

(48) Except the way of Hell, to dwell therein for ever. And this to Allah is easy.

(49) And call in remembrance the favour of Allah unto you, and His covenant, which He ratified with you, when ye said: "We hear and we obey": And fear Allah, for Allah knoweth well the secrets of your hearts.

(50) O ye who believe! stand out firmly for Allah, as witnesses to fair dealing, and let not the hatred of others to you make you swerve to wrong and depart from justice. Be just: that is next to piety: and fear Allah. For Allah is well-acquainted with all that ye do.
