Hadith 5172
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "The one who commits adultery is not a believer while committing adultery. The one who steals is not a believer while stealing. The one who drinks alcohol is not a believer while drinking alcohol." Ibn Shihab says: Abdul Malik bin Abu Bakr bin Abdur Rahman informed me that Abu Bakr bin Abdur Rahman narrated this to those people on the authority of Sayyiduna Abu Hurairah (may Allah be pleased with him). Along with this, he would add these words: "A person who snatches a valuable thing while people are watching him is not a believer while snatching it."
