The system was a special society headed by the leader of the system, who was the one in charge.

As for the issue of "hijra," we find its origin in the system. It came from Islamic thought, which is based on the Sanusiyya on one hand, and the requirements of the movement on the other hand. It can also be said, following the example of the Prophet (peace be upon him), on a third hand.

The idea of "hijra" is based on the principle that a Muslim individual must migrate from his country if it is occupied by infidels and he is unable to practice his religious teachings there, to an Islamic country to live under Islamic rule. Zubada says that the Sanusiyya adopted this idea of migration, which was first advocated by Al-Sharif Al-Shafi'i (died 1245 AD). Ibn Al-Sanusi, on the other hand, believes that this idea is what prompted Ibn Al-Sanusi to leave Algeria and settle in Cyrenaica. There is no doubt that this idea was found among Muslim thinkers, and the jurists based their opinion on it on many religious evidence after they created the terms "Dar al-Islam" (the abode of Islam) from which to migrate, and "Dar al-Harb" (the abode of war) from which to migrate.

However, Ibn Al-Sanusi did not migrate from Algeria for this reason alone. In our opinion, the main reason is that he was a preacher and could not carry out his mission under the infidel French rule. This was after he considered returning, as Ibn Al-Sanusi left Algeria before the French occupied it, in our opinion.

It should not be overlooked that most of the inhabitants of Algeria and all other Islamic countries migrated when their Muslim lands were occupied by Western colonizers. Some followers of the Sanusiyya in Algeria remained in their country and fought the enemy, although some others migrated.
