Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "No one of you should drink while standing." 
                                                     
                                                                                                    
[Authentic hadith] - [Narrated by Muslim]                                            
The Hadīth includes the forbiddance to drink while standing. This forbiddance applies when there is no need to drink while standing, and it indicates dislike of doing that.
