Abu Ayyub al-Ansari

Abu Ayyub al-Ansari, born Khalid ibn Zayd in Medina, belonged to the Banu Najjar clan of the Banu Khazraj tribe. He was one of the Ansar who supported Prophet Muhammad after the Hijra and hosted the Prophet in his house. He played a significant role as a standard-bearer and was involved in numerous military campaigns from Muhammad's time through the caliphate of Muawiyah I. Abu Ayyub was the waqif of the land for Al-Masjid an-Nabawi and served as governor of Medina under Caliph Ali. In his final campaign, he participated in the siege of Constantinople, where he died and was buried near the city walls. His descendants spread across the Arabian Peninsula and the Indian subcontinent.
