`Abd Allah al-Zubayr or ibn Zubayr (Arabic: عبد الله بن الزبير 'Abdallāh ibn az-Zubayr; 624 - 692) was an Arab sahabi whose father was Zubayr ibn al-Awwam, and whose mother was Asma bint Abi Bakr, daughter of the first Caliph Abu Bakr. He was the nephew of Aisha, Prophet Muhammad's third wife.
He was a member of the Bani Assad tribe and was born one year and 8 months after the hijra of Muhammad to Madinah. As such, he was the first Muslim child born in Madinah. As a young man, Abd Allah was an active participant in numerous Muslim campaigns against both the Byzantine and Sassanid empires. He marched to Sbeitla, Tunisia, the capital of self-proclaimed local emperor Gregory the Patrician. Gregory was defeated and killed in the Battle of Sufetula in 647 CE.
