6:159 O Messenger! Those who break the unity of their Deen and become sects, you have nothing to do with them whatsoever. Their case will go to God and He will then tell them what they had done.
All those divided into several sects like Sunni, Shia, Dev Bandi, Baralvee, Ahle Hadees etc are disobeying the Quran and Quran has thrown such people out of Islam fold and stamped them as hypocrites.
The event of Karbala is all false, invented by Persian fake Imam Rustam bin Tabari who wrote story 250 years later of the event. He was not an eyewitness either.
My questions to all, if Imam Hussain (RA) was a power hungry person?
