SHAFAQNA – It is narrated from the Prophet of Islam (PBUH) who said: When beliefs and opinions against true religious doctrine (heresies) do appear, it is the duty of the experts in religion to tell the truth. The curse of Allah (SWT) be on the one who conceals the truth . Without doubt, the Ashura holy movement was based on the Quran and the traditions of the Prophet of Islam (PBUH) for reforming the society and to remedy the extensive damage the Ummah (Islamic nation) suffered gradually after the Prophet (PBUH) until the time of Ashura.
