Its not sharifian. Its sharif ain.
شریف عین
We call then sharif ain because we are syed Hashimiz but from 3rd wife of Ali R.A
They are from Daughter of Prophet Mihammad PBUH another wife of Ali R.A
They are our half brothers. We are called syed by many in iran, Iraq pakistan india. Central asia.
Sharif ain have direct lineage to the survivor brother. Its not islamic history as history of islam ends with end of Prophet Mohammed PBUH's life on earth.
Anyways when he comes no one will be able to doubt his credentials
even the ones who hate him would not be able to defy him because he will have mahority of muslims shia suni and all that crap with him.
That day there will be no shia or sunni only muslims. No arabs or turks no pakistani or chinese all will be known as muslim only.
The label shia or sunni digust me to my core.
