Therefore, Al-Sanusi was known as Al-Idrisi Al-Hassani. It is worth mentioning that Ibn Al-Sanusi used to write his name in full in his letters as follows: Muhammad bin Ali bin Al-Sanusi Al-Khattabi Al-Hassani Al-Idrisi.

His Date of Birth The historians of the Sanusiya differ in determining the date of birth of Ibn Al-Sanusi, although a large number of them agree on one date and set it as the 11th of Rabi' al-Awwal of the year 1202 AH, which corresponds to December 1787 AD. As for those who differed from this date, most of them are foreign historians such as Adams, Stoddard, Ren, Dupont, and Kobolani. The latter two... We adopt the date from Ren, who provided an approximate date, which is around the first... and we believe it to be correct because it is the date mentioned by the early historians of the Sanusiya who lived at the same time as Ibn Al-Sanusi and were his relatives. What confirms the correctness and accuracy of this date is that it coincided with the anniversary of the birth of the Prophet (peace be upon him), which is preserved as a religious occasion. This coincidence was highlighted by Sheikh Al-Islam, especially in Morocco. In his translation of Ibn Al-Sanusi, he stated in the introduction to "Al-Manhal Al-'Adhb" (The Sweet Spring): "Our Sheikh, Sayyid Muhammad bin Ali Al-Sanusi Al-Khattabi Al-Idrisi was born in the Middle Maghreb in the year 1202 AH, on the 11th of Rabi' al-Awwal, and thus he was named Muhammad." Ahmad Al-Sharif also noted this in his book "Al-Kawkab Al-Zahir" (The Shining Star): "May God be pleased with him, he was born in the year two hundred and twelve of the thirteenth century, on a Monday, the second..."

The Use of the Title "Ibn Al-Sanusi" The title "Ibn Al-Sanusi" is used when referring to him because it is the title by which the people of Cyrenaica refer to him. Some historians have used the title "Al-Sanusi Al-Kabir" (The Great Sanusi).
