This book is a detail exposition of the end time Messiah. It is an unparalleled source material, which you, the reader, never read before because scholars wrote to explain the Messiah or Imam Mahdi; but now, Mashiach ben David or Imam Mahdi personally explain himself
The book is written from 6 different perspectives to give:

Ahl-al Bayt evidence
Historical evidence
Eschatological evidence
National evidence
Scriptural evidence
Astronomical evidence

Ahl-al Bayt evidence explains Imam Mahdi ("the Guided One") as a prince in Kano; and give his genealogy as a descendant of the prophet Muhammad pbuh], the messenger of Allah and the Khatam-an Nabieen.
Historical evidence explains the 6 items, which the real Imam Mahdi ("the Guided One") would fulfill to distinguish him from the false Messiah and Mahdi claimants.
Eschatological evidence explains the end time prophecy of the Beast (دابة من الأرض) in the Holy Qur'an. It describes the Beast as a Sign of the Hour.
National evidence explains the Messiah, Mashiach ben David AKA Imam Mahdi, who was prophesied in the ancient sacred scriptures of the Abrahamic religions, as a citizen of an independent country, federal republic of Nigeria, in the modern world.
Scriptural evidence explains Imam Mahdi as the witness who is endowed with the secret Knowledge of the Book, which remained unknown to both the Islamic Ulema' and the Orientalists since the revelation of the Qur'an, until the messiah came to the world.
Astronomical evidence explains the unparalleled sign of Imam Mahdi ("the Guided One"). This was the twin lunar and solar eclipses in the Saros series cycle 111 and 137, which occurred in 1894 AD. Moreover, it exposes the mistake of Mirza Ghulam Ahmad who claimed to be the promised messiah and Imam Mahdi "without knowledge" (22:3) that the real Imam Mahdi was predestined to come, and issue the proclamation 126 years after the eclipses
Imam Mahdi ("the Guided One") is prophesied in the Holy Qur'an. He is as prophesied as a Witness as well as the Beast; the witness is prophesied in 13:43, using 15-letter phrase: (ومن عنده علم الكتب); and the Beast, a Sign of the Hour, is prophesied in 27:82, using an 11-letter phrase: (دابة من الأرض). On the other hand, the 1894-eclipse season contain 2 eclipses: Partial Lunar Eclipse in the Saros Series 111 and Hybrid Solar Eclipse in the Saros Series 137, which occurred on 21 Mar, 1894 AD and 6 Apr, 1894 AD respectively.
The eclipses were the two unparalleled signs of Imam Mahdi, prophesied by the prophet Muhammad pbuh], in hadith literature; and the 2 eclipses complement the 2 prophecies of Imam Mahdi in the Qur'an to show that the real Imam Mahdi would issue the proclamation 126 years after the eclipses

A] Prophecy of the Witness
If you add: Saros Series 111 ]15-letter phrase] = 126
B] Prophecy of the Beast
If you subtract: Saros Series 137 - 11-letter phrase] = 126

Of a surety I issued the proclamation to the United Nations on 7th June 2020; and that was exactly 126 years after the 1894-eclipses Therefore I am the real Imam Mahdi ("the Guided One")
