Jami` at-Tirmidhi Book 26, Hadith 22
"The Prophet (ﷺ) drank from Zamzam while he was standing."
He said: There are narrations on this topic from 'Ali, Sa'd, 'Abdullah bin 'Amr and 'Aishah.
This Hadith is Hasan Sahih.
"The Prophet (ﷺ) prohibited drinking while standing."
And there are narrations on this topic from Abu Sa'eed, Abu Hurairah, and Anas. And this Hadith is Hasan Gharib. This Hadith was reported from other narrators, from Sa'eed, from Qatadah, from Abu Muslim, from Al-Jarud, that the Prophet (ﷺ) said: "The Muslim's wandering (animal) stirs the Fire." Al-Jarud bin Al-Mu'alla is called Ibn Al-'Al' but what is correct is Al-Mu'alla.
From his father, from his grandfather who said: "I saw the Messenger of Allah (ﷺ) drinking while standing and sitting."
This Hadith is Hasan Sahih.
