Objectively, meaning without any doctrinal bias. The early Muslim scholars classified oral/written reports after examining chain of transmission, biographical evaluation, etc. and placed reports under two classes:
Mutawatir- This means mass transmitted. Meaning that the chain of narrators is so numerous that it leads back to a large number of the companions of Muhammad (S). An example, 62 witnesses heard one man saying “my favourite colour is black” and everyone without exception heard him make this statement, it is absurd to assert that not only did all of them mishear what the man actually said, but even more absurd, perhaps empirically impossible, to assert that they heard the exact same thing from the moment they misheard the statement. This is why a Mutawatir report is Sahih (meaning authentic) by default.
Ahad- Linguistically this means a single chain of transmission, but could mean multiple chains of narrators, just not a large amount of chains. Ahad reports are further examined and placed under four categories. Sahih (meaning authentic), Hasan (meaning reliable), Daif (meaning weak), and Mawdu (meaning fabricated).
The early scholars did not simply accept or reject reports based on doctrinal bias, like the Shias did/do.
Thats not objectively verifying anything scientifically.
You are misusing the term ‘empiric’. It doesnt belong with hearsay from 600AD.
AD meaning after the birth of Jesus Christ.
However, oral tradition and eye witness is very much how we Catholics got the Bible and our Church Teachings. And, of course The Holy Spirit.
You know of course that Jesus Christ is the First Priest of the One, Holy and Apostolic Church.
For the New Testament:
Jesus Christ taught,
Early scholars who were there , or had witness information,
wrote the teachings and Miracles of Jesus Christ down.
You guys had only 62 witnesses?
For the Loaves and Fishes Miracle, over 5000 men alone!
For the Passion of Our Lord JESUS CHRIST, many thousands, and the Historical records of the Roman Empire, and the Jews. And of course , the Christians.
For the birth of Our Lord JESUS CHRIST, three wise men, shepherds, the Jewish historical records , Herod knew and killed off all children under 2 to try to kill Our Lord, Jesus Christ,
FOR running demons into 2000 pigs, then over cliffs, an entire town as witness.
But you havent answered the question. How on earth can you scientifically and objectively verify there are virgins, waiting, in your heaven for those who kill non muslims?
Our Lord, Jesus Christ God. said ‘thou shalt not kill’
And sins of the flesh will get you a one way trip to hell.
Do you think what Boko Haram did, and Daesh are doing in kidnapping and raping, or killing women who refuse is ok with God? Or do you believe Daesh and Boko Haram are Demonic?
