The ninth day of Rabi al-Awwal, one day after the martyrdom of Imam Hasan Askari (AS), is the day that Shiites commemorate the beginning of the Wilayat and Imamate of Hazrat Mahdi (AS).

One of the most sensitive and important actions of Imam Hassan Askari (AS) was to introduce his son to the Shia community.

This issue was sensitive because, on the other hand, the enemies of Imam Zaman (A.S.) were trying to find him and bring him to martyrdom. Because according to many traditions, they knew that a child would be born from the Ahl al-Bayt (PBUH) family who would be the savior of the world and the destroyer of oppressors and would not swear allegiance to the oppressive system like their fathers.

Therefore, they took several measures to prevent the birth of that child and even planned the murder of Imam Hasan Askari (a.s.). As in the hadiths, the birth of Imam Zaman (AS) has been compared to the birth of Prophet Moses (AS).
