The word(s) "leaf" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Pickthal translation.

(1) And with Him are the keys of the Invisible. None but He knoweth them. And He knoweth what is in the land and the sea. Not a leaf falleth but He knoweth it, not a grain amid the darkness of the earth, naught of wet or dry but (it is noted) in a clear record.

(2) And for the moon We have appointed mansions till she return like an old shrivelled palm-leaf.
