Rashid bin Sa’d says that when Istakhr was conquered, a caller announced, “O people! Beware, the Dajjal has appeared.” During this, they met Sayyiduna Sa’b bin Jaththamah (may Allah be pleased with him), who said, “If you do not say this, I will tell you that I heard the Prophet (peace and blessings be upon him) say: The emergence of the Dajjal will not occur until people forget his mention and the imams stop mentioning him on the pulpits.”
