Hadith al-Iftiraq is a famous Hadith attributed to Prophet Muhammad (s) in many Shi‘i and Sunni Hadith collections, as well as in heresiographical sources. Among many books written by contemporary heresiographers, few have failed to mention this Hadith in their writings. Many Shi‘i and Sunni traditionists have collected the traditions that deal with the future of the Muslim ummah under such titles as the Hadith of fitan (tribulations), iftiraq al-ummah (division of ummah), or ittiba‘ sunan man mada (lit., following the ways of those who have passed). However, it seems that none of the above traditions have been more welcomed by heresiographers and apologists than the Hadith iftiraq al-ummah. This article will analyze this Hadith and its different versions and various interpretations, especially the identity of the only sect that, according to the Hadith, will be saved in the Hereafter.
