Abu Sa'id Khudri reported that Allah's, Messenger (may peace he upon him) forbade from turning the waterskins upside down and drinking from their mouths

This hadith has been reported from Zuhri with the same chain of transmitters, but he also said that Ikhtinath means that its head (i. e., of the waterskin) be turned upside down and then (water) be drank from that
