SHAFAQNA – Fazil narrated from Imam Sadiq (AS) who said: When our Qa’em [Imam Mahdi (AJ)] appears, the harm and bother inflicted on him by ignorant people will be more than the ignorant pagans inflicted on the Prophet (PBUH). I asked Imam (AS); how? Imam Sadiq (AS) replied: At the start of the prohethood of the Prophet of Islam (PBUH), people used to worship carved stone and wood but at the time of the appearance of our Qa’em everyone will commentate (according to his/her opinion and views) about the Book of God and (with own interpretation) will reason against Imam Mahdi (AJ). Imam Sadeq (AS) then added: Swear to Allah (SWT), (Qa’em) will spread his justice like heat and cold in people’s houses and no one is capable of escaping his justice .
