This is the age of Science and Technology and we must analyze all the truth under the two subjects.
The Persian fake Imam Tabari invented the fake story of Karbala and wrote his book 250 years later of the so-called event. He was not an eye witness. He made a big bloody fool out of the believers and until today all are following the fiction story.
The worldly courts need an eye witness of the event or written proof duly signed by the two parties of the event which are not there. The courts normally throw such cases out of windows.
Before Tabari, there were certain writers like Abu Hanifa, Shafi, Malik, Hanbal, Bukhari, Muslim, Abu Dawood, Nissai, Tirmizi, etc never mentioned a single word of Karbala. So much so Imam Zain ul Abideen wrote a book and never talked about the suffering of his parents at Karbala. Tabari has written that Imam Zain ul Abideen was sick, lying in the tent at the sit of Karbala.
