It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) said: "The adulterer is not a believer at the time he commits adultery, the thief is not a believer at the time he steals, and the one who drinks wine is not a believer at the time he drinks it."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Yahya (may Allah have mercy on him) except Muhammad (may Allah have mercy on him)."
