Imam Hasan al-Mujtaba —upon whom be peace— was the second Imam. He and his brother Husayn were the two sons of Amir al-mu’minin ‘Alī and Lady Fātimah, the daughter of the Prophet. He was born in the year 3 A.H. in Medina . The Prophet came to ‘Ali’s home, congratulated the new parents and named the child, on Allāh’s order, as “Hasan”.
