أبو أيوب الأنصاري
The land of Al-Masjid an-Nabawi belonged to two young orphans, Sahl and Suhayl, and when they came to know that Muhammad wished to acquire their land for the purposes of erecting a mosque, they went to Muhammad and offered the land to him as a gift; Muhammad insisted on paying a price for the land because they were orphaned children. The price agreed upon was paid by Abu Ayyub al-Ansari, who thus became the endower or donor () of Al-Masjid an-Nabawi on behalf of, or in favor of, Muhammad. al-Ansari also accommodated Muhammad upon his arrival at Madinah in 622.
