Introduction Whatever disagreement may arise regarding this issue, which determines the year of the Mahdi's emergence or the year of the establishment of the Second Rightly Guided Caliphate, I respond to those who criticize this with the following points: - It has been stated by many scholars that such an interpretation is permissible, and I particularly mention in our time the scholar Muhammad Al-Sadiq Al-Maghribi, who said (meaning): that it is permissible as an indication and for the good and optimism it contains.

- This is merely a matter of seeking good omens and of the good optimism that our Sheikh Al-Sadiq advocated, and it aligns with transmitted texts and narrations from the past, and with the scientific principle: that any unseen matter is referred to the Messenger of Allah (peace be upon him), if its path is not through the People of the Book, because it is a matter in which ijtihad and opinion are not applicable.

- This chapter is a continuation of the chapter on the signs of the Mahdi's emergence, but I wanted everyone to read it, so I shortened its pages, so that many would be encouraged to read it. Whoever wants more should follow the rest of the volumes and their topics.

- I have based the hypothesis of numbers and dates on our current time. If it is correct, it is from Allah, and if it is not—and this is unlikely—then the error is from Satan.

Important Note I will rely on the year thirty-seven, which was mentioned in the previous text from Ibn Mas'ud, may Allah be pleased with him, who said: The Messenger of Allah (peace be upon him) said: "The millstone of Islam will revolve for thirty-five, or thirty-six, or thirty-seven years. Then they will perish as those who perished before. If it is completed, it will be seventy years." (Al-Fitan by Nu'aym bin Hammad) From Abu Qabil, he said: "The people will unite on the Mahdi in the year two hundred and twenty-four, according to the Persian calculation, not the Arab calculation." (Al-Fitan by Nu'aym bin Hammad) The correct Gregorian calendar is the (Ethiopian) calendar, which differs from the current Gregorian calendar by seven years. This is also the disagreement regarding the time of the birth of Christ, peace be upon him, between winter and summer, due to the general Quranic verses and texts from the Gospel of Matthew. The Gregorian calendar was adjusted during the Gregorian era—the birth of Christ, peace be upon him—and was advanced by seven years. All Christian nations followed this altered calendar, which is currently used in all countries of the world and their institutions, except for the Ethiopian people, who refused to alter the Gregorian calendar and continued with the calendar of the birth of Christ, peace be upon him. Therefore, the Ethiopian calendar is seven years and nine months later than the Gregorian calendar.
