Is tattooing forbidden in Islam? What kind of drawing and shape is forbidden? And if a tattoo does not cause harm, is it still forbidden?

Tattooing, which involves piercing the skin with a needle and then filling it with kohl or other substances, is forbidden because it alters Allah’s creation. The Prophet Muhammad (peace be upon him) cursed the tattooist and the one who gets a tattoo, and this act is considered among the major sins. However, if it is not permanent on the body, then it is not considered a tattoo and does not involve altering Allah’s creation.
