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

(1) Thus did he lead them on with guile. And when they tasted of the tree their shame was manifest to them and they began to hide (by heaping) on themselves some of the leaves of the Garden. And their Lord called them, (saying): Did I not forbid you from that tree and tell you: Lo! Satan is an open enemy to you?

(2) Then they twain ate thereof, so that their shame became apparent unto them, and they began to hide by heaping on themselves some of the leaves of the Garden. And Adam disobeyed his Lord, so went astray.
