In the (Stoning of the Devil) is a symbol of recognizing and combatting the enemy. If, one day, the Muslim world and Islamic Ummah became free from the many enemies, the reason behind Bara’at (disavowal) would be gone. But with so many adversaries and enmities today, neglecting the enemy and ignoring the importance of Bara’at would be a grave and very damaging mistake.
