What is the ruling on al-Hurquṣ?

If what is meant by "Harqus" is temporary tattoo, then it is permissible and does not fall under the prohibited tattooing. However, if it refers to a small creature (like a tick or a flea), then the majority of scholars prohibit eating it because it is considered repulsive, and Allah has made lawful the good things and forbidden the evil things, as He says: {They ask you, [O Muhammad], what has been made lawful for them. Say, "All good foods have been made lawful for you"} and His saying: {and makes lawful for them the good things and prohibits for them the evil things}.
