Ash-Shaykh Abdul-Muhsin al-Abaad, may Allah preserve him, was asked the following question,
Question:
السؤال: ما حكم شرب المرء قائماً؟ وهل نقول لمن شرب قائماً: إنك آثم؟
What is the ruling of a person drinking standing and is it allowed for us to say to the one drinking standing that you are sinning?
Answer:
الجواب: لا نقول له: إنك آثم، بل نقول: إن الشرب حال الجلوس هو الأولى والأفضل، والشرب حال القيام جائز.
We shouldn’t say to him you are sinning. Rather, we say drinking when sitting is more preferable and better, while drinking when standing is permissible
Reference: Sharh Sunnan Abu Dawuud (055).
