Anas bin Malik reported,

She milked a domestic sheep for the Messenger of Allah ﷺ while she was in the house of Anas bin Malik, and his milk was mixed with water from the well in the house of Anas. She gave the cup to the Messenger of Allah ﷺ and he drank from it. When he removed the cup from his mouth, Abu Bakr was on his left and an Arabi was on his right.Umar, fearing that he would give it to the Arabi, said, "Messenger of Allah, give it to Abu Bakr who is near you."But he gave it to the Arabi who was on his right, then said, "The one on the right, then the next on the right."

أنس بن مالك رضي الله عنه

أنها حلبت لرسول الله ﷺ شاة داجن وهي في دار أنس بن مالك وشيب لبنها بماء من البئر التي في دار أنس فأعطى رسول الله ﷺ القدح فشرب منه حتى إذا نزع القدح من فيه وعلى يساره أبو بكر وعن يمينه أعرابي فقال عمر وخاف أن يعطيه الأعرابي أعط أبا بكر يا رسول الله عندك فأعطاه الأعرابي الذي على يمينه ثم قال الأيمن فالأيمن
