The word(s) "trace" appears 2 time(s) in 2 verse(s) in Quran in Saheeh International translation.

(1) Say, [O Muhammad], "Have you considered that which you invoke besides Allah? Show me what they have created of the earth; or did they have partnership in [creation of] the heavens? Bring me a scripture [revealed] before this or a [remaining] trace of knowledge, if you should be truthful."

(2) Muhammad is the Messenger of Allah; and those with him are forceful against the disbelievers, merciful among themselves. You see them bowing and prostrating [in prayer], seeking bounty from Allah and [His] pleasure. Their mark is on their faces from the trace of prostration. That is their description in the Torah. And their description in the Gospel is as a plant which produces its offshoots and strengthens them so they grow firm and stand upon their stalks, delighting the sowers - so that Allah may enrage by them the disbelievers. Allah has promised those who believe and do righteous deeds among them forgiveness and a great reward.
