Once, at the request of a friend of my mother, I wrote Sura al Fatiha (in Arabic) so that later these verses could be inscribed on a tombstone.
Will this sin be forgiven me if I do tawba or, in addition to tawba, I definitely need to contact my mother’s friend and explain to her that it is forbidden to write the verses of the Quran on the tombstone, since by my actions I indirectly confirmed the permissibility of inscribing the verses of the Quran on the tombstone?
