1) Permissible medicines are allowed. Allah provides you a cure through them.
2) If a person has tattoos before Islam, or if they repent from them and surgery is too expensive to remove them - then Allah has forgiven the past sins.
Dr. Muzammil Siddiqi, former president of the Islamic Society of North America, states the following:
“First of all, I would like to stress the fact that it is
haram to have tattoos on the body. However, the Prophet (peace and blessings be upon him) is reported to have said,
“Islam takes away the sins done before it.”
Thus, if these tattoos cannot be removed easily or if you have to spend a lot of money to remove them, then you should not worry about them.
