Burning of Elegy Books (Marsiyas):

Question: If a person possesses elegies that are recited for the martyrs of Karbala during rituals such as Ta'ziya, and he wishes to dispose of them, what should he do?

Answer: It is necessary to either burn them or bury them in the ground to ensure that this affliction does not spread elsewhere.
