The word(s) "faces" appears 45 time(s) in 41 verse(s) in Quran in Abdullah Yusuf Ali translation.

(21) If only the Unbelievers knew (the time) when they will not be able to ward off the fire from their faces, nor yet from their backs, and (when) no help can reach them!

(22) There are among men some who serve Allah, as it were, on the verge: if good befalls them, they are, therewith, well content; but if a trial comes to them, they turn on their faces: they lose both this world and the Hereafter: that is loss for all to see!

(23) When Our Clear Signs are rehearsed to them, thou wilt notice a denial on the faces of the Unbelievers! they nearly attack with violence those who rehearse Our Signs to them. Say, "Shall I tell you of something (far) worse than these Signs? It is the Fire (of Hell)! Allah has promised it to the Unbelievers! and evil is that destination!"

(24) The Fire will burn their faces, and they will therein grin, with their lips displaced.

(25) Those who will be gathered to Hell (prone) on their faces,- they will be in an evil plight, and, as to Path, most astray.

(26) And if any do evil, their faces will be thrown headlong into the Fire: "Do ye receive a reward other than that which ye have earned by your deeds?"

(27) The Day that their faces will be turned upside down in the Fire, they will say: "Woe to us! Would that we had obeyed Allah and obeyed the Messenger!"

(28) On the Day of Judgment wilt thou see those who told lies against Allah;- their faces will be turned black; Is there not in Hell an abode for the Haughty?

(29) But how (will it be) when the angels take their souls at death, and smite their faces and their backs?

(30) Muhammad is the messenger of Allah; and those who are with him are strong against Unbelievers, (but) compassionate amongst each other. Thou wilt see them bow and prostrate themselves (in prayer), seeking Grace from Allah and (His) Good Pleasure. On their faces are their marks, (being) the traces of their prostration. This is their similitude in the Taurat; and their similitude in the Gospel is: like a seed which sends forth its blade, then makes it strong; it then becomes thick, and it stands on its own stem, (filling) the sowers with wonder and delight. As a result, it fills the Unbelievers with rage at them. Allah has promised those among them who believe and do righteous deeds forgiveness, and a great Reward.
