The Prophet (may Allah's peace and blessings be upon him) invoked the curse, expulsion, and removal from the mercy of Allah Almighty upon four categories: First: A woman who adds hair extensions for herself or for another. Second: A woman who asks for hair extensions to be added to her hair. Third: The one who tattoos, which involves piercing the skin with a needle in a part of the body, such as the face, hand, or chest, and inserting kohl or similar substances into it until it leaves a bluish or greenish mark, seeking adornment and beauty. Fourth: The one who asks to be tattooed. Such acts are from the major sins.
