Your consciousness about religion is commendable. As far as tattoos
are concerned, it is better if you are able to do away with them. However,
if you are not able to there is no need to fret over them. Your prayers and
fasts would hopefully be counted because before God it is the sincerity of
heart and mind that counts more than any other thing.
True repentance of a person spiritually cleanses him. Just as water
physically cleans a person, repentance wipes out all sins and wrongs.
