The word(s) "straight" appears 64 time(s) in 64 verse(s) in Quran in Abdullah Yusuf Ali translation.

(21) "I put my trust in Allah, My Lord and your Lord! There is not a moving creature, but He hath grasp of its fore-lock. Verily, it is my Lord that is on a straight Path.

(22) Therefore stand firm (in the straight Path) as thou art commanded,- thou and those who with thee turn (unto Allah); and transgress not (from the Path): for He seeth well all that ye do.

(23) And they set up (idols) as equal to Allah, to mislead (men) from the Path! Say: "Enjoy (your brief power)! But verily ye are making straightway for Hell!"

(24) (Allah) said: "This (way of My sincere servants) is indeed a way that leads straight to Me.

(25) And unto Allah leads straight the Way, but there are ways that turn aside: if Allah had willed, He could have guided all of you.

(26) Allah sets forth (another) Parable of two men: one of them dumb, with no power of any sort; a wearisome burden is he to his master; whichever way be directs him, he brings no good: is such a man equal with one who commands Justice, and is on a straight Way?

(27) He showed his gratitude for the favours of Allah, who chose him, and guided him to a straight Way.

(28) Give full measure when ye measure, and weigh with a balance that is straight: that is the most fitting and the most advantageous in the final determination.

(29) (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,

(30) But when they reached the Junction, they forgot (about) their Fish, which took its course through the sea (straight) as in a tunnel.
