Lady Aisha (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) entered the house of a woman from the Ansar. There was a hanging water-skin in her house. The Prophet (peace and blessings be upon him) turned its mouth and drank water from it while standing.

Sayyiduna Anas (may Allah be pleased with him) narrates that my mother, Sayyida Umm Sulaym (may Allah be pleased with her), told me that the Noble Prophet (peace and blessings be upon him) came to her, and there was a water-skin hanging in the house. He drank water from it while standing. I cut off the mouth of that water-skin and kept it with me.
