Anas told that a domestic sheep was milked for God’s messenger and its milk was mixed with water from a well in Anas’s house. God’s messenger was then given a cup and drank, Abu Bakr being on his left and a nomadic Arab on his right. ‘Umar asked God’s messenger to give it to Abu Bakr, but he gave it to the nomadic Arab who was on his right saying, “He who is on the right, then he who is on his right.” A version has, “Those on the right, then those on their right; go to the right.”*
*This tradition indicates that people should band a drink to the one on their right irrespective of the relative importance of the people present. The tradition immediately following brings this out clearly.
(Bukhari and Muslim.)
Anas said that God's messenger used to breathe three times in the course of a drink.
(Bukhari and Muslim.) In a version Muslim added that he used to say, "It is more thirst-quenching, healthier and more wholesome."
Abu Sa'id al-Khudri said God’s messenger forbade the ikhtibath of water-skins, adding in a version that this means having their heads inverted and then being drunk from.
(Bukhari and Muslim.)
