Salam Aulakum my brothers and sisters,
For some, tattoos are repulsive and scaring, for others they are seen with beauty and self expression.
Tattoos are certainly a taboo topic in the muslim community as there are Hadiths calling tattoos pagan, damaging, repulsive and forbidden In Islam.... however not exactly! Because for the Shias Imam Ali (as) we have four separate Hadiths as we Shias view the Sunni Hadiths such as sahih, muslim, bukari and many more as corrupted so that Hadith is also ignored by Shias.
Which opens up tattoos for the Shias, but which tattoos and what are completely to they’re marjas, my marja (ayatollah Hakim) allows portraits of the infallibles and religious texts on appropriate parts of the body but forbids living creatures,
It really depends on the marja you follow.
I hope this little post helped open your minds a little.
