The word(s) "aye" appears 206 time(s) in 183 verse(s) in Quran in Abdullah Yusuf Ali translation.

(91) Their purpose was to scare thee off the land, in order to expel thee; but in that case they would not have stayed (therein) after thee, except for a little while.

(92) Establish regular prayers - at the sun's decline till the darkness of the night, and the morning prayer and reading: for the prayer and reading in the morning carry their testimony.

(93) And pray in the small watches of the morning: (it would be) an additional prayer (or spiritual profit) for thee: soon will thy Lord raise thee to a Station of Praise and Glory!

(94) "Or thou cause the sky to fall in pieces, as thou sayest (will happen), against us; or thou bring Allah and the angels before (us) face to face:

(95) Say: "Call upon Allah, or call upon Rahman: by whatever name ye call upon Him, (it is well): for to Him belong the Most Beautiful Names. Neither speak thy Prayer aloud, nor speak it in a low tone, but seek a middle course between."

(96) Such (being their state), we raised them up (from sleep), that they might question each other. Said one of them, "How long have ye stayed (here)?" They said, "We have stayed (perhaps) a day, or part of a day." (At length) they (all) said, "Allah (alone) knows best how long ye have stayed here.... Now send ye then one of you with this money of yours to the town: let him find out which is the best food (to be had) and bring some to you, that (ye may) satisfy your hunger therewith: And let him behave with care and courtesy, and let him not inform any one about you.

(97) So they stayed in their Cave three hundred years, and (some) add nine (more)

(98) Say: "Allah knows best how long they stayed: with Him is (the knowledge of) the secrets of the heavens and the earth: how clearly He sees, how finely He hears (everything)! They have no protector other than Him; nor does He share His Command with any person whatsoever.

(99) And they will be marshalled before thy Lord in ranks, (with the announcement), "Now have ye come to Us (bare) as We created you first: aye, ye thought We shall not fulfil the appointment made to you to meet (Us)!":

(100) Wherein they shall dwell (for aye): no change will they wish for from them.
