Wether it be in Judaism, in Christianism or in Islam, the apocalyptic literature has scrutinized the founding writs to find clues, « omens » indicating the upcoming of « the Hour » in order to be prepared for it and to make sense of the dreaded terror. In Islam, that search has taken a particular form : today as well as yesterday, to fill in the silence of the Qur’an, a profusion of accommodating hadiths, inspired by judeo-christian apocalyptic writings, unleashes speculations geared to pious needs but also to legitimacy claims for unrestrained political acivism. This paper briefly examines how islamic apolcapyptic tradition was constructed and then shows that some trends of that construction process nowadays proliferate exponentially in the blogosphere.
