SHAFAQNA – The Imamate of Imam Hussain (AS) was coincided with the time of two Omayyad rulers, Moawieh and his son Yazid. Moawieh formed a vast and lavish kingdom which was not anything like the Islamic government. He used all the tools in his disposal to weaken people’s culture and thought and by forming sects, tried to move away the people from real Islam and by creating wars, managed to eliminate many of those who were seeking justice.
It is narrated from the Prophet of Islam (PBUH) who said: Whatever was in the previous people, without any change is in this Ummah (nation) . In dialogue between Imam Reza (AS) and Mamoon, Mamoon asked: What do you say about returning (Roj’at)? Imam (AS) replied: That has happened in previous nations and is also mentioned in Quran and the Prophet (PBUH) said: Whatever has happened in the previous Ummah, will happen in this Ummah without any change .
As it happened at the time of Prophet Moses (AS) when Sameri and his companions in the absence of Moses, displaced his deputy Haroon and tried to kill him . The Sameris of the (Islamic) Ummah displaced the Caliph of the Prophet (PBUH) from leadership and guidance of the society as well as plotted to kill him and eventually did it.
