What was the Prophet Muhammad (saw) accustomed to drink from when at Medina?
 Narrated Abu Burda:                     When I arrived at Medina, `Abdullah bin Salam met me and said to me, "Accompany me to my house so that I may make you drink from a bowl from which Allah's Apostle used to drink, and that you may offer prayer in the mosque in which the Prophet used to pray." I accompanied him, and he made me drink Sawiq and gave me dates to eat, and then I prayed in his mosque.
