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

(51) "For me, I intend to let thee draw on thyself my sin as well as thine, for thou wilt be among the companions of the fire, and that is the reward of those who do wrong."

(52) They thought there would be no trial (or punishment); so they became blind and deaf; yet Allah (in mercy) turned to them; yet again many of them became blind and deaf. But Allah sees well all that they do.

(53) O ye who believe! Allah doth but make a trial of you in a little matter of game well within reach of game well within reach of your hands and your lances, that He may test who feareth him unseen: any who transgress thereafter, will have a grievous penalty.

(54) Allah made the Ka'ba, the Sacred House, an asylum of security for men, as also the Sacred Months, the animals for offerings, and the garlands that mark them: That ye may know that Allah hath knowledge of what is in the heavens and on earth and that Allah is well acquainted with all things.

(55) Allah will say: "This is a day on which the truthful will profit from their truth: theirs are gardens, with rivers flowing beneath,- their eternal Home: Allah well-pleased with them, and they with Allah: That is the great salvation, (the fulfilment of all desires).

(56) To Him belongeth all that dwelleth (or lurketh) in the night and the day. For He is the one who heareth and knoweth all things."

(57) It is He who created the heavens and the earth in true (proportions): the day He saith, "Be," behold! it is. His word is the truth. His will be the dominion the day the trumpet will be blown. He knoweth the unseen as well as that which is open. For He is the Wise, well acquainted (with all things).

(58) Say: "Shall I seek for judge other than Allah? - when He it is Who hath sent unto you the Book, explained in detail." They know full well, to whom We have given the Book, that it hath been sent down from thy Lord in truth. Never be then of those who doubt.

(59) One day will He gather them all together, (and say): "O ye assembly of Jinns! Much (toll) did ye take of men." Their friends amongst men will say: "Our Lord! we made profit from each other: but (alas!) we reached our term - which thou didst appoint for us." He will say: "The Fire be your dwelling-place: you will dwell therein for ever, except as Allah willeth." for thy Lord is full of wisdom and knowledge.

(60) "O Adam! dwell thou and thy wife in the Garden, and enjoy (its good things) as ye wish: but approach not this tree, or ye run into harm and transgression."
