The word(s) "marks" appears 5 time(s) in 5 verse(s) in Quran in Muhammad Pickthal translation.

(1) Between them is a veil. And on the Heights are men who know them all by their marks. And they call unto the dwellers of the Garden: Peace be unto you! They enter it not although they hope (to enter).

(2) And the dwellers on the Heights call unto men whom they know by their marks, (saying): What did your multitude and that in which ye took your pride avail you?

(3) And landmarks (too), and by the star they find a way.

(4) And if We would, We could show them unto thee (Muhammad) so that thou shouldst know them surely by their marks. And thou shalt know them by the burden of their talk. And Allah knoweth your deeds.

(5) The guilty will be known by their marks, and will be taken by the forelocks and the feet.
