Possible Biblical Interpretations
In their book, Al Mahdi and the End of Time, Muhammad ibn Izzat and Muhammad Arif, two well-known Egyptian authors, identify the Mahdi in the Book of Revelation, quoting the hadith narrator Ka'ab al-Ahbar.
In one place, they write,
“I find the Mahdi recorded in the books of the Prophets... For instance, the Book of Revelation says: “And I saw and behold a white horse. He that sat on him went forth conquering and to conquer.”Ibn Izzat and Arif then go on to say:
“It is clear that this man is the Mahdi who will ride the white horse and judge by the Qur’an (with justice) and with whom will be men with marks of prostration (zabiba) on their foreheads.”Read more about this topic: Imam Mehdi
