He also reported God’s messenger as saying, “When one commits fornication he is not a believer, when one steals he is not a believer, when one drinks wine he is not a believer, when one takes plunder on account of which men raise their eyes at him he is not a believer, and when one of you defrauds he is not a believer; so beware, beware!" (Bukhari and Muslim.) The version of Ibn ‘Abbas contains “When one commits murder he is not a believer.” ‘Ikrima said that he asked Ibn 'Abbas how faith could be snatched away from him, and he replied “Thus (interlacing his fingers and then separating them), but if he repents, it will return to him thus,” and he interlaced his fingers. Aba ‘Abdallah1 said that such a one is not a perfect believer and does not possess the light of faith. This is Bukhari's wording. 1 i.e. ‘Ikrima, Abu Abdullah being his kunya.
