Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The fornicator is not a believer while he commits fornication; the thief is not a believer while he steals; the drinker of wine is not a believer while he drinks it." We said: "O Messenger of Allah! How will that be?" The Prophet (peace and blessings be upon him) said: "Faith departs from that person; if he repents, faith returns to him."
Tabarani recorded it in al-Mu'jam al-Awsat, and al-Bazzar also recorded it. Tabarani's chain contains a narrator, Muhammad bin Abd al-Rahman bin Abi Layla, whom al-Ijli declared thiqah (trustworthy), while Ahmad and others declared him da'if (weak) because of his poor memory.
