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

(141) And on them, as well as in ships, ye ride.

(142) O ye messengers! enjoy (all) things good and pure, and work righteousness: for I am well-acquainted with (all) that ye do.

(143) Repel evil with that which is best: We are well acquainted with the things they say.

(144) If ye find no one in the house, enter not until permission is given to you: if ye are asked to go back, go back: that makes for greater purity for yourselves: and Allah knows well all that ye do.

(145) Say to the believing men that they should lower their gaze and guard their modesty: that will make for greater purity for them: And Allah is well acquainted with all that they do.

(146) Allah is the Light of the heavens and the earth. The Parable of His Light is as if there were a Niche and within it a Lamp: the Lamp enclosed in Glass: the glass as it were a brilliant star: Lit from a blessed Tree, an Olive, neither of the east nor of the west, whose oil is well-nigh luminous, though fire scarce touched it: Light upon Light! Allah doth guide whom He will to His Light: Allah doth set forth Parables for men: and Allah doth know all things.

(147) Seest thou not that it is Allah Whose praises all beings in the heavens and on earth do celebrate, and the birds (of the air) with wings outspread? Each one knows its own (mode of) prayer and praise. And Allah knows well all that they do.

(148) Seest thou not that Allah makes the clouds move gently, then joins them together, then makes them into a heap? - then wilt thou see rain issue forth from their midst. And He sends down from the sky mountain masses (of clouds) wherein is hail: He strikes therewith whom He pleases and He turns it away from whom He pleases, the vivid flash of His lightning well-nigh blinds the sight.

(149) They swear their strongest oaths by Allah that, if only thou wouldst command them, they would leave (their homes). Say: "Swear ye not; Obedience is (more) reasonable; verily, Allah is well acquainted with all that ye do."

(150) Be quite sure that to Allah doth belong whatever is in the heavens and on earth. well doth He know what ye are intent upon: and one day they will be brought back to Him, and He will tell them the truth of what they did: for Allah doth know all things.
