Abu Sa'id al-Khudri reported that the Messenger of Allah said, "The Mahdi will be of my stock and will have a broad forehead and a hooked nose. He will fill the earth with equity and justice as it was previously filled with oppression and tyranny, and he will rule for seven years." (Abu Dawud) Part of Allah's justice and wisdom is that near the end of time He will send a man to restore justice in the earth and to confront the Dajjal. This will be the Mahdi. One aspect of Allah's bounty is that before the Mahdi appears there will appear certain clear signs. He will have certain traits and unique characteristics which do not exist in anyone else. True Muslims will recognize them and not be deceived by false claimants. This book presents the evidence in the Qur'an and the Sunna for the truth of the Mahdi and mentions the signs which will precede him.
