Hisham narrates from his father, from Sayyidah Aishah (may Allah be pleased with her), the story of the emigration (Hijrah) of the Prophet (peace and blessings be upon him) and his departure from Makkah with Abu Bakr (may Allah be pleased with him), that when the two of them set out, Amir bin Fuhayrah (may Allah be pleased with him) was with them, and the two of them took turns riding with him, until they reached Madinah.
