The word(s) "mark" appears 13 time(s) in 13 verse(s) in Quran in Saheeh International translation.

(1) Yes, if you remain patient and conscious of Allah and the enemy come upon you [attacking] in rage, your Lord will reinforce you with five thousand angels having marks [of distinction]

(2) O you who have believed, do not violate the rites of Allah or [the sanctity of] the sacred month or [neglect the marking of] the sacrificial animals and garlanding [them] or [violate the safety of] those coming to the Sacred House seeking bounty from their Lord and [His] approval. But when you come out of ihram, then [you may] hunt. And do not let the hatred of a people for having obstructed you from al-Masjid al-Haram lead you to transgress. And cooperate in righteousness and piety, but do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty.

(3) And between them will be a partition, and on [its] elevations are men who recognize all by their mark. And they call out to the companions of Paradise, "Peace be upon you." They have not [yet] entered it, but they long intensely.

(4) And the companions of the Elevations will call to men [within Hell] whom they recognize by their mark, saying, "Of no avail to you was your gathering and [the fact] that you were arrogant."

(5) marked from your Lord. And Allah 's punishment is not from the wrongdoers [very] far.

(6) And landmarks. And by the stars they are [also] guided.

(7) For you the animals marked for sacrifice are benefits for a specified term; then their place of sacrifice is at the ancient House.

(8) And they say, "What is this messenger that eats food and walks in the markets? Why was there not sent down to him an angel so he would be with him a warner?

(9) And We did not send before you, [O Muhammad], any of the messengers except that they ate food and walked in the markets. And We have made some of you [people] as trial for others - will you have patience? And ever is your Lord, Seeing.

(10) And if We willed, We could show them to you, and you would know them by their mark; but you will surely know them by the tone of [their] speech. And Allah knows your deeds.
