Narrated 'Eisa bin 'Abdullah bin Unais:
From his father who said: I saw the Prophet (ﷺ) standing at a hanging water-skin, so he bent it, then drank from it.
He said: There is something on this topic from Umm Salamah.
[Abu 'Eisa said:] The chain of this Hadith is not Sahih. 'Abdullah bin 'Umar Al-'Umari (a narrator in the chain) was graded weak due to his memory, and I do not know if he heard from 'Eisa or not.
