Knowing the Sirah of the Sahaba & Ahl Al-Bayt is something every Muslim should strife for, especially the great figures amongst them such as Al-Hussein Ibn Ali Ibn Abi Talib. Now the problem is that the net is filled with Rafidi exaggeration and lies, they flooded the net (just as the Chrstians flooded the net with THEIR version of Jesus), so it is sometimes frustrating. Of course there are LOADS of books in Arabic (even classical books and in Tarikh books such as in the ‘Al-Bidayah wa Al-Nihayah’ of the student of Ibn Taymiyyah, i.e. Hafidh Ibn Kathir you will find lots of information about the tragedy of Karbala), yet most of them are not translated (heck many creed books are not even translated yet).
There is one book we would like to recommend (click on the image to download):
The book is basically a compilation of various Muslims (Sunni) sources in regards to the tragedy of Karbala.
