What is the Sharee'ah ruling concerning a person who drinks alcohol and eats during the day in Ramadhaan?

All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.

It is quite clear that drinking alcohol and not fasting in Ramadan without an excuse are major grave sins. Anyone who does so claiming it to be lawful or does it out of haughtiness and objection to the ruling of Allaah becomes a disbeliever; otherwise, he is a wrongdoer who exposes himself to great danger.

Allaah Knows best.
