Abdullah ibn Hasan
Abdullah ibn Hasan (Arabic: عبدالله بن حسن) was the son of Hasan ibn Ali. He went to Karbala with his uncle Husayn ibn Ali, and was Martyred at the Battle of Karbala. Also, his name has been mentioned in Ziyarat al-Nahiya al-Muqaddasa. According to Shia Muslims, Abdullah ibn Hasan was only 11 years old when he got martyred in the Battle of Karbala. During the last moments of Husayn ibn Ali's life, Bahr Ibn Ka’ab was about to strike him when Abdullah came running out of the tents. He stood in his way and  shouted "O, son of the corrupt woman! Are you going to strike my uncle?". The brave boy shielded Husayn from the stroke of the sword, whereby his hand got cut and began to dangle. Abdullah cried "O, uncle". Husayn took hold of his nephew, drew him to his chest and said "O, son of my brother! Bear patiently what you have suffered, and consider it good, because Allah will make you meet your pious forefathers." At that point Harmala bin Kahil threw an arrow at Abdullah, and martyred him in his uncle's arms.
