and the price of the land was paid for by Abu Bakr. The Muslims, including Abu Bakr, constructed a mosque named Al-Masjid al-Nabawi at the site. Abu Bakr was paired with Khaarijah bin Zaid Ansari (who was from Medina) as a brother in faith. Abu Bakr's relationship with Khaarijah was most cordial, which was further strengthened when Abu Bakr married Habiba, a daughter of Khaarijah. Khaarijah bin Zaid Ansari lived at Sunh, a suburb of Medina, and Abu Bakr also settled there. After Abu Bakr's family arrived in Medina, he bought another house near Muhammad's. While the climate of Mecca was dry, the climate of Medina was damp and because of this, most of the migrants fell sick on arrival.

In these stories subsequently Abu Bakr, along with other companions, led Muhammad to a place of safety. Battle of Uhud In 625, he participated in the Battle of Uhud, in which the majority of the Muslims were routed and he himself was wounded. Before the battle had begun, his son Abd al-Rahman, at that time still non-Muslim and fighting on the side of
