If a drunk person drinks from a vessel, is it permissible for me to drink from that vessel?

"If the questioner is asking about the permissibility of drinking from a vessel that a drunk person drank from, then the answer is that there is no objection to it after washing and purifying it. However, if the question is about drinking from the leftovers of a wine drinker, then if the wine is apparent on his mouth at the time of drinking, then if the drink is food, it becomes impure as soon as it comes into contact with the wine. And if the drink is water and it has been changed by the wine, then it is also impure. If it has not been changed, then it is impure according to the majority. According to the Malikis, a small amount of water does not become impure with a small impurity that does not change any of its characteristics. And if the wine has no remaining presence on his mouth, then his leftover is not impure and its use is permissible, but it is preferable to avoid associating with the immoral and drinking their remnants.
