The word(s) "may" appears 366 time(s) in 309 verse(s) in Quran in Abdullah Yusuf Ali translation.

(141) But say not - for any false thing that your tongues may put forth,- "This is lawful, and this is forbidden," so as to ascribe false things to Allah. For those who ascribe false things to Allah, will never prosper.

(142) It may be that your Lord may (yet) show Mercy unto you; but if ye revert (to your sins), We shall revert (to Our punishments): And we have made Hell a prison for those who reject (all Faith).

(143) We have made the Night and the Day as two (of Our) Signs: the Sign of the Night have We obscured, while the Sign of the Day We have made to enlighten you; that ye may seek bounty from your Lord, and that ye may know the number and count of the years: all things have We explained in detail.

(144) We have explained (things) in various (ways) in this Qur'an, in order that they may receive admonition, but it only increases their flight (from the Truth)!

(145) "Or created matter which, in your minds, is hardest (to be raised up),- (Yet shall ye be raised up)!" then will they say: "Who will cause us to return?" Say: "He who created you first!"

(146) Your Lord is He That maketh the Ship go smoothly for you through the sea, in order that ye may seek of his Bounty. For he is unto you most Merciful.

(147) (He hath made it) Straight (and Clear) in order that He may warn (the godless) of a terrible Punishment from Him, and that He may give Glad Tidings to the Believers who work righteous deeds, that they shall have a goodly Reward,

(148) Further, that He may warn those (also) who say, "Allah hath begotten a son":

(149) That which is on earth we have made but as a glittering show for the earth, in order that We may test them - as to which of them are best in conduct.

(150) 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.
