The word(s) "leaves" appears 21 time(s) in 21 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) In the result, they both ate of the tree, and so their nakedness appeared to them: they began to sew together, for their covering, leaves from the Garden: thus did Adam disobey his Lord, and allow himself to be seduced.

(12) Then the Blast overtook them with justice, and We made them as rubbish of dead leaves (floating on the stream of Time)! So away with the people who do wrong!

(13) Nay, the wrong-doers (merely) follow their own lusts, being devoid of knowledge. But who will guide those whom Allah leaves astray? To them there will be no helpers.

(14) Is he, then, to whom the evil of his conduct is made alluring, so that he looks upon it as good, (equal to one who is rightly guided)? For Allah leaves to stray whom He wills, and guides whom He wills. So let not thy soul go out in (vainly) sighing after them: for Allah knows well all that they do!

(15) Allah has revealed (from time to time) the most beautiful Message in the form of a Book, consistent with itself, (yet) repeating (its teaching in various aspects): the skins of those who fear their Lord tremble thereat; then their skins and their hearts do soften to the celebration of Allah's praises. Such is the guidance of Allah: He guides therewith whom He pleases, but such as Allah leaves to stray, can have none to guide.

(16) Is not Allah enough for his Servant? But they try to frighten thee with other (gods) besides Him! for such as Allah leaves to stray, there can be no guide.

(17) "A Day when ye shall turn your backs and flee: No defender shall ye have from Allah: Any whom Allah leaves to stray, there is none to guide...

(18) For any whom Allah leaves astray, there is no protector thereafter. And thou wilt see the Wrong-doers, when in sight of the Penalty, Say: "Is there any way (to effect) a return?"

(19) And no protectors have they to help them, other than Allah. And for any whom Allah leaves to stray, there is no way (to the Goal).

(20) Or He bestows both males and females, and He leaves barren whom He will: for He is full of Knowledge and Power.
