Imam Hasan Al-Mujtaba (A.S) was an active participant in the Jung-e-Jamal (Battle of camel where Ayesha the daughter of Abu Bakr and also the wife of Prophet Muhammad s.a.w.a.s. led her fanatic bunch against Imam Ali. It was Islam’s first civilian war and it was due to Ayesha’s visceral hate for Prophet’s family resulted in thousands losing their lives).
In one of the attacks, Imam Ali (a.s.) gave his spear to his younger son, Mohammad Hanafia, and told him to fight with it…
Hanafia and killed many but when he faced a strong group of enemies from Bani Zebba he couldn’t get the better of them and had to retreat back to his father.
Imam Hasan (a.s.) took the spear and entered the battle like a lion. Such was the intensity of his warfare that the colour of his spear had turned red with the enemies’ blood.
He then returned to his father. When Mohammad Hanafia saw him, he dropped his head in embarrassment and his face turned red.
Imam Ali (a.s.) said, “Don’t look down upon yourself, because he is son of Our Prophet (s.a.w.a.s.) but you are Ali’s son.”
