In the question below, the questioner inquired Did Yazid order to kill Imam Hussein (a.s)? and it would prove it historically. (by historical proof). But a moderator (gold Pseudo) put the answers on hold.
In the answers of the respondents, they have mentioned historical narrations and likewise the speech of Yazid (about a letter…), to prove (historically) that Yazid ordered..., such as Al-Dahabi, Al-Suyuti, Musafi Ibn Sharih, Tzkiratul Khawas of Sibt Ibn Jauzi and so forth. And I reckon these were authentic and good enough to prove the issue. But as I said, a moderator put it on hold, so I was wondering how we shall prove a matter by historical proof if these answers really are not appropriate?
