The word(s) "well" appears 236 time(s) in 217 verse(s) in Quran in Mohsin Khan translation.

(181) So know (O Muhammad صلى الله عليه وسلم) that, La ilaha illallah (none has the right to be worshipped but Allah) , and ask forgiveness for your sin, and also for (the sin of) believing men and believing women. And Allah knows well your moving about, and your place of rest (in your homes).

(182) When those who disbelieve had put in their hearts pride and haughtiness - the pride and haughtiness of the time of ignorance, - then Allah sent down His Sakinah (calmness and tranquillity) upon His Messenger (صلى الله عليه وسلم) and upon the believers, and made them stick to the word of piety (i.e. none has the right to be worshipped but Allah); and they were well entitled to it and worthy of it. And Allah is the All-Knower of everything.

(183) Verily those who call you from behind the dwellings, most of them have no sense.

(184) Denied before them (i.e. these pagans of Makkah) the people of Nuh (Noah), and the dwellers of Rass, and Thamud;

(185) And the Dwellers of the Wood, and the people of Tubba'. Everyone of them denied (their) Messengers, so My Threat took effect.

(186) Those who avoid great sins (See the Qur'an, Verses: 6:152,153) and Al-Fawahish (illegal sexual intercourse) except the small faults, - verily, your Lord is of Vast Forgiveness. He knows you well when He created you from the earth (Adam), and when you were fetuses in your mothers' wombs. So ascribe not purity to yourselves. He knows best him who fears Allah and keeps his duty to Him [i.e. those who are Al-Muttaqun (the pious. See V.2:2)].

(187) So on that Day no question will be asked of man or jinns as to his sin, [because they have already been known from their faces either white (dwellers of Paradise - true believers of Islamic Monotheism) or black (dwellers of Hell - polytheists; disbelievers, criminals)].

(188) In a Book well-guarded (with Allah in the heaven i.e. Al-Lauh Al-Mahfuz ).

(189) On the Day you shall see the believing men and the believing women: their light running forward before them and by their right hands. Glad tidings for you this Day! Gardens under which rivers flow (Paradise), to dwell therein forever! Truly, this is the great success!

(190) And those who believe in (the Oneness of) Allah and His Messengers - they are the Siddiqun (i.e. those followers of the Prophets who were first and foremost to believe in them), and the martyrs with their Lord, they shall have their reward and their light. But those who disbelieve (in the Oneness of Allah - Islamic Monotheism) and deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) - they shall be the dwellers of the blazing Fire.
