<b>Guidance from the Hadiths:</b><br> 1) The forbiddance of drinking while standing denotes actual prohibition; yet a prohibited thing may be done sometimes because of need.<br> 2) The Prophet’s command that a man should induce vomit indicates that it is strongly prohibited to drink while standing.<br> Note:<br> What the author (may Allah have mercy upon him) said in Chapter "the permissibility to drink while standing and clarifying that drinking while sitting is better and more perfect" does not agree with the apparent meaning of the reported texts. In fact, the Prophet (may Allah’s peace and blessings be upon him) only drank while standing because of need. Hence, it is permissible to drink while standing when needed. On the other hand, there are numerous Hadiths giving stern warnings about drinking while standing, including<br> Hadiths cited by the author - “He forbade drinking while standing”; “He disapproved drinking while standing”; and “None of you should drink while standing, and whoever forgets, let him induce vomit” - and other Hadiths in which the Prophet (may Allah’s peace and blessings be upon him) commanded drinking while sitting. As part of a long Hadith, he said to Abu Hurayrah (may Allah be pleased with him): “Sit down and drink.” So, based on the various forms of prohibition of drinking while standing and the emphatic command to drink while sitting, it becomes clear that we are required to drink while sitting, except if the situation necessitates otherwise, like being in a crowded place or it is not possible to sit down. And Allah knows best. In Fat'h al-Bāri Sharh Sahih al-Bukhāri, for Ibn hajar al-‘Asqalāni summarized this issue in the following verses:<br> (the reward of) following the Sunnah of the Prophet<br> When you drink, sit down, so you will win.<br> But that was only to denote permissibility<br> They authentically reported that he drank while standing
