First let me start by saying, i know humans wrote the Hadith, and that the Hadith are not protected like the Quran from corruption. There seems to be a contradiction in hadith regarding whether or not it is permissible to drink water (or eat) while standing.
Forbidden to Drink Water/Eat:
Book 023, Number 5018:
Anas reported that Allah's Apostle (may peace be upon him) forbade that a person should drink while standing. Qatada reported: We said to him: What about eating? Thereupon he (Anas) said: That is even worse and more detestable (abominable).
Book 023, Number 5022:
Abu Huraira reported Allah's Messenger (may peace be upon him) as saying: None of you should drink while standing; and if anyone forgets, he must vomit.
Allowed to Drink While Standing:
Book 023, Number 5025:
Ibn 'Abbas reported that Allah's Apostle (may peace be upon him) drank (water) from Zamzam while he was standing.
So, what is it, can i no eat or drink while standing, and must i vomit when i forget? Or can i drink while standing?
