On this element, they reached conclusions that seem unsuccessful to us (we will explain this later). If we return to the first element to rely on it as a basis, we find that the date of death of Al-Mahdi is definitively determined as the year 524 AH, leaving no room for doubt. The narratives are inconsistent regarding the year of death. So, if his birth year ranges between 469 AH and 474 AH. We can take a step further in precision and suggest that Ibn Tumart's age at his death was 51 years. Ibn Athir and Al-Nuwayri mention him first in their narration, which suggests preference. Also, the word "one" is missing from the narration of "Mafakhir al-Barbar," making his statement "... and he was fifty-one years old." When we rely on this preference, the most likely year for Ibn Tumart's birth becomes 473 AH. This seems closer to the truth. This choice does not preclude the possibility that his age at his journey to the East to seek knowledge exceeded 50 years, as the date of departure was the year 473 AH. This is a very late age for those who travel to seek knowledge, because it seems that Moroccans travel to the East to seek knowledge at a later age due to the long distance and hardship of travel. As for those who travel early, they are often accompanied by their fathers or some of their relatives, as is the case with Abd al-Mu'min bin Ali, who intended to travel to the East at the age of eighteen accompanied by his father. As is the case with Ibn al-Gharbi, who traveled at the age of sixteen accompanied by his father. This is what Goldziher went for, as he considered the word "youth" to indicate an age of around twenty, usually based on a misunderstanding of Al-Ghazali's saying, "in the prime of my youth, from puberty before twenty," and this saying can only indicate a point in youth that extends beyond thirty (See: Goldziher - Muhammad ibn Tumart, p. 41). Also, this is what Buruih went for, suggesting the year 485 AH for Ibn Tumart's birth (See his book - Muhammad ibn Tumart, p. 19 and onwards). This is from this research. (See p. 128). (See: Al-Baydaq - Akhbar al-Mahdi, p. 38). Ibn al-Arabi was born in 468 AH and traveled in 485 AH. (See: Ammar Talbi - Opinions of Abu Bakr ibn al-Arabi on Kalam, p. 25 and onwards).
