It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that Allah's curse is upon the woman who plucks hair, the one who files teeth, the one who joins someone else's hair with her own, the one who tattoos, and the one who changes Allah's creation. And why should I not curse the one whom the Prophet (peace and blessings be upon him) has cursed? Upon this, a woman from Banu Asad said, "What if the women of your household do this?" Sayyiduna Ibn Mas'ud (may Allah be pleased with him) replied, "Go and see." The woman went to his house, then came back and said, "I did not find anything objectionable there, but I do not find this command in the Qur'an." He replied, "Why not? This is what the Prophet (peace and blessings be upon him) has said."
