If a person travels from one station to another without a ticket, which is not permissible, then he should calculate the fare for the number of times he traveled without a ticket, purchase the tickets, and destroy (discard) them. In this way, Insha'Allah, he will be absolved of his responsibility, because in this situation, the due right reaches the rightful owner. (Aham Masail / Vol: 5 / Pg: 232)
