It is narrated from Hazrat Umm Sulaym (may Allah be pleased with her) that once the Prophet (peace and blessings be upon him) came to her house. There was a water-skin hanging in her house. The Prophet (peace and blessings be upon him) stood and drank water from the mouth of that water-skin. Afterwards, she cut off the mouth of that water-skin (from which the Prophet, peace and blessings be upon him, had drunk) and kept it with her.
