The Messenger of Allah (may Allah's peace and blessings be upon him) visited me and drank from the mouth of a hanging waterskin while he was standing. So, I got up and cut off its mouth
Umm Thābit, Kabshah bint Thābit, sister of Hassān ibn Thābit, (may Allah be pleased with both of them) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) visited me and drank from the mouth of a hanging waterskin while he was standing. So, I got up and cut off its mouth.
