Are tattoos allowed or not in Islam? If they are not allowed, please explain the details.
Tattoo is Haraam
Because we have no right to change the creation of allah.
Narrated 'Abdullah: Allah has cursed those women who practise tattooing and those who get themselves tattooed, and those who remove their face hairs, and those who create a space between their teeth artificially to look beautiful, and such women as change the features created by Allah. Why then should I not curse those whom the Prophet has cursed? And that is in Allah's Book. i.e. His Saying: 'And what the Apostle gives you take it and what he forbids you abstain (from it).' (Quran 59.7)
