Hadith 15:458
Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from al-Zuhri, who heard it from Anas, he said: The Prophet (peace and blessings of Allah be upon him) arrived in Medina when I was ten years old, and he (peace and blessings of Allah be upon him) passed away when I was twenty years old. My mothers used to urge me to serve him. He entered our house, and we milked for him from a domestic sheep of ours, and mixed it with water from a well in the house. Abu Bakr was on his left, a Bedouin was on his right, and ‘Umar was to the side. ‘Umar said: "O Messenger of Allah, give to Abu Bakr." But he gave to the Bedouin and said: "The one on the right, then the one on the right."
حدثنا أبو بكر قال حدثنا بن عيينة عن الزهري سمعه من أنس قال قدم النبي صلى الله عليه وسلم المدينة وأنا بن عشر وتوفي صلى الله عليه وسلم وأنا بن عشرين وكن أمهاتي يحثثنني على خدمته فدخل علينا دارنا فحلبنا له من شاة داجن لنا وشيب له من بئر في الدار وأبو بكر عن شماله وأعرابي عن يمينه وكان عمر ناحية فقال عمر يا رسول الله أعط أبا بكر فأعطى الأعرابي وقال الأيمن فالأيمن
