What is the ruling on "adhesive tattoos" that can be removed without leaving a trace, knowing the prohibition and harms of permanent tattoos, and that henna is an alternative but is flawed by its lack of precision and its long-lasting nature?

Tattooing differs from dyeing in that tattooing is a permanent alteration of the skin's color, and it is considered forbidden because it is an alteration of Allah's creation. It has three forbidden forms: needling, using chemicals or surgery to change skin color, and temporary tattoos that last a long time (more than a year). As for dyeing with henna, it does not permanently change skin color; rather, it is a permissible temporary adornment, provided that the designs are not in the form of living beings, and that the adornment is not displayed to a non-mahram man.

As for "temporary tattoos" that disappear after a short period (less than a year), they are permissible on condition that they are temporary, do not contain designs of living beings, that the adornment is not displayed to non-mahrams, that they do not cause harm to the skin, and that they do not involve imitation of immoral women or disbelievers, or bear forbidden symbols. Additionally, any health harm resulting from the "tattoo" makes it legally prohibited.
