Ka'b :Amir al-Muminin, you ought to write your will because you will die in three days.
Umar : How do you know that ?
Ka'b : I found it in the Book of God, the Taurat (Old Testament).
Umar : By God do you find Umar Ibn al-Khattab in the Old Testament?
Ka'b : By God, no. But I found your description in the Old Testament and your time is coming to an end.
Umar : But I do not feel any pain or sickness
On the following day Ka'b came to Umar and said : Amir al-Mu'minin, one day has passed and you have only two more days.
The following day Ka'b came to him and said : Amir al-Mu'minin, two days have gone and you have only one day and one night remaining.
The following morning Abu Lulu appeared carrying a dagger with two heads and a handle in the middle. He hit Umar six times, one of them hit the Caliph in the navel, killing him.
Note: Torah is only the first 5 books of Judaism, not the whole "old testament"
What did Ka'ab actually saw in Torah? Encoded message? Any historical hadists on this?
Note 2: I am not a muslim. I am an agnostic examining supernatural claims of religions.
