Q: “Is it allowed to eat while standing?”
“There is no legislative text to prohibit eating while standing like the text that prohibits drinking while standing. But there is a narration from Anas bin Maalik رضي الله عنه that when he told those around him in a gathering that the Prophet ﷺ prohibited drinking while standing, someone said to him: ‘What about eating (while standing)?’ and he replied: ‘It is worse.’
I say here, we should follow this Companion because we don’t have anything with which we can contradict him. But what is the distinction between eating while standing and eating while walking? Eating while walking is allowed, because there is legislative text clearly stating that they used to eat while walking during the time of the Prophet ﷺ. As for eating while standing, there is no such text regarding it from the Prophet ﷺ, neither negative nor positive. All we have is this authentic narration from Anas bin Maalik and this is what we act upon.
Moreover, maybe some of you noticed in these times that it has become a fashion for disbelievers to eat while standing although chairs are available; but they don’t sit on them out of pride. In that case, the previous ruling is further strengthened. So we are with the narration of Anas because Anas knew what we don’t know, and because disbelievers nowadays and Muslims who imitate them eat while standing, hence we differ from them.”
