Overview
Abd-Allah ibn al-Husayn, also known as Ali al-Asghar, 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, who first surrounded them for some days and cut off their access to the nearby river Euphrates.

There are further confusions as some Shia and Sunni authors variously refer to one of these two sons as Ali al-Asghar. Among them are the polymath Abu Hanifa Dinawari and the fifteenth-century historian Hasan ibn Muhammad Qomi, the author of .
