I saw the Prophet ﷺ go up to a waterskin that was hanging, fold its mouth back, and drink from its opening.
حدثنا يحيى بن موسى حدثنا عبد الرزاق أخبرنا عبد الله بن عمر
رأيت النبي ﷺ قام إلى قربة معلقة فخنثها ثم شرب من فيها

Its chain is daif. Abu Dawud narrated it in the Book of Drinks, chapter on bending the mouths of waterskins, no. 3721, from the hadith of Abdullah bin Umar Umari, and he is daif in narrations from other than Nafi, and Isa bin Abdullah is mastur, not deemed reliable by anyone other than Ibn Hibban.There is also a narration on this topic from Umm Salim [Ahmad 6/376, 431 and Darimi, no. 2130].
