The word(s) "palm-trees" appears 5 time(s) in 5 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) (Pharaoh) said: "Believe ye in Him before I give you permission? Surely this must be your leader, who has taught you magic! be sure I will cut off your hands and feet on opposite sides, and I will have you crucified on trunks of palm-trees: so shall ye know for certain, which of us can give the more severe and the more lasting punishment!"

(2) And tall (and stately) palm-trees, with shoots of fruit-stalks, piled one over another;-

(3) Plucking out men as if they were roots of palm-trees torn up (from the ground).

(4) Whether ye cut down (O ye Muslim!) The tender palm-trees, or ye left them standing on their roots, it was by leave of Allah, and in order that He might cover with shame the rebellious transgresses.

(5) He made it rage against them seven nights and eight days in succession: so that thou couldst see the (whole) people lying prostrate in its (path), as they had been roots of hollow palm-trees tumbled down!
