These two honorable Imams (AS) are brothers of each other and are the sons of Imam Ali (AS) and Fatimah (AS). According to the authentic Islamic Traditions, the Holy Prophet (SA) had deep affections towards these honorable grandsons whom he called his own sons.

The Holy Prophet (SA) was not able to endure their slightest pain and dissatisfaction and used to state: “These two sons of mine are Imams and leaders, be they rising or sitting”.

The terms ‘rising’ and ‘sitting’ are used symbolically and signify taking charge of leadership and rising to fight with the enemies of Islam and non- acceptance of superficial khilafah (Ruler of an Islamic State) and rising against it.

The Holy Prophet (SA) also said “Hasan and Husayn are the two leaders of the youth of the Heaven.”
