Chapter: The religious learned men should not differ
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 Messenger (ﷺ) used to drink, and that you may offer prayer in the mosque in which the Prophet (ﷺ) 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.
