The Hadith of

One of the seemingly complex events in early Islam is the wars between Muslims themselves during the caliphate of Ali Ibn-e- Abitaleb, so that some of the great Companions of the Prophet Muhammad (PBUH & HP) remained doubtful for a time about which one of the two warning groups is rightful. A few studies have been carried out concerning the causes, nature and consequences of these battles, but few comprehensive studies based on documentary sources have been made about these wars and the doubts raised in this respect. One of these important events is the battle of Siffin, where Ammar Yasser was martyred by Muawiya forces. It is reported in a hadith narrated by several authorities that the Prophet (pbuh) said: He (Ammar ibn Yasir) will be killed by Al-fi’at baghiya (insolent band). The very idea of Ammar's fighting alongside Imam Ali clearly indicates Imam Ali's rightful position, in general and falsehood of Muawiyah and his insolent forces, in particular. Raising doubts about the authenticity of this hadith, Ibn Taymiyyah express his overwhelming support to Muawiya, and thus it is very important to make semiotic analysis of his invalid reasons and justifications. The doubts he raises about the chain of transmission of the Hadith and claiming that its textual implication is weak, considering Muawiyah's conduct as Ijtihad for which he will be rewarded despite the mistake he made in ijtihad and so on are amongIbn Taymiyyah's dubious ideas, which this research seeks to examine critically, concentrating on Sunni historical sources and hadith books.
