595–674 CE

He founded the garrison city of Kufa in Iraq, which became a significant center of early Islamic learning and politics. He was one of the ten companions promised Paradise (al-'ashara al-mubashsharun) and one of the six members of the shura council appointed by Umar رضي الله عنه to choose the next caliph.

His victory at al-Qadisiyyah is a foundational event of Islamic history — the moment when Islam expanded beyond Arabia and became a world civilization.

His military legacy established the model of rapid, decisive conquest that characterized the early Islamic expansion.
