Ali al-Asghar ibn Husayn

Abd-Allah ibn al-Husayn (Arabic: عَبْد ٱللَّٰه ٱبْن ٱلْحُسَيْن), also known as Ali al-Asghar (Arabic: عَلِيّ ٱلْأَصْغَر, lit. 'Ali, the junior'), was the youngest son of Husayn ibn Ali, the grandson of Muhammad and the third Shia Imam. A young child, likely an infant, he was killed in the Battle of Karbala in 680 CE, alongside his father, family members, and a small number of supporters, all of whom were massacred by the forces of the Umayyad caliph Yazid (r. 680–683), who first surrounded them for some days and cut off their access to the nearby river Euphrates. Abd-Allah is commemorated in Shia Islam as the quintessence symbol of the innocent victim.
