A Brief View of the Holy Call

A Brief View of the Holy Call

In a Narration about Imam Al Baqir (PBUH) (There is no banner better than that of the banner of Yamani, it is the banner of faith and dedication, because he calls to your possessor, so if the Yamani comes out, selling weapons to people or any Muslim becomes prohibited, and if the Yamani appears, stand up to him, because he’s banner is the banner of faith, and its prohibited for any Muslim to turn away from him, and who ever turns away from him, then he’s from the people of hell, because he calls to the truth and to the right path).
Here we have the right to ask:
If this flag is of such important importance, and who ever ignores it goes to hell, and the case is clear by standing up to him, then why not set any details??
