If all the Shiites abandon mourning and weeping for the master of the martyrs, Imam Hussein(AS), no harm will inflict the great rituals of Imam Hussein peace be upon him, because Allah the Wise, will never allow anyone to extinguish or distort these rituals. In case, people let go of Imam Hussein,s mourning ceremonies and rituals , only the very people themselves will suffer damage and become despised and shameful on the Day of Resurrection.
