Chapter 114
Permission to Drink while in a standing Posture

767. Ibn `Abbas (May Allah be pleased with them) reported: I served Messenger of Allah (sallallaahu ’alayhi wa sallam) Zamzam water to drink and he drank it while he was standing.
[Al-Bukhari and Muslim].

768. An-Nazzal bin Sabrah (May Allah be pleased with him) reported: `Ali bin Abu Talib (May Allah be pleased with him) arrived at Bab Ar-Rahbah (in Kufah) and drank water in a standing posture. Then he said: “I saw Messenger of Allah (sallallaahu ’alayhi wa sallam) doing what you have seen me doing.”
[Al-Bukhari].

769. Ibn `Umar (May Allah be pleased with them) reported: During the lifetime of Messenger of Allah (sallallaahu ’alayhi wa sallam) we would eat while walking and would drink while standing.
[At-Tirmidhi].

770. `Amr bin Shu`aib on the authority of his father and grandfather reported: that they saw Messenger of Allah (sallallaahu ’alayhi wa sallam) drink standing, and sitting.
[At-Tirmidhi].

The last three Ahadith point out the permissibility of eating and drinking while walking or standing or sitting, but drinking in the sitting position remains the best.

771. Anas (May Allah be pleased with him) reported: The Prophet (sallallaahu ’alayhi wa sallam) forbade us from drinking while standing. Qatadah reported: “We asked him: `What about eating?”’ He said: “That is even worse, (or may be he said) more detestable.”

 Another narration is: Messenger of Allah (sallallaahu ’alayhi wa sallam) reprimanded us for drinking while standing.
[Muslim].

772. Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (sallallaahu ’alayhi wa sallam) said, “None of you should drink standing; and if any one forgets, he must vomit.”
[Muslim].
