"Narrated by Gaber bin Abdullah: We were with the messenger of Allah, PBUH and he asked for a drink. One of his men said: "Oh Messenger of Allah, Can we offer you wine to drink?" He said Yes. He (Gaber) went out looking for the drink and came back with a cup of wine. The messenger (PBUH) asked:”Have you fermented it, even with one piece of ferment?” He (Gaber) said "yes" and he (Muhammad) drank." - Sahih Muslim 3753 (read more)

"The person who knows the truth and believes in it, then turns his back on it, does not deserve to live. The punishment for apostasy is prescribed for the protection of the religion and as a deterrent to anyone who is thinking of leaving Islaam. There is no doubt that such a serious crime must be met with an equally weighty punishment. If the kuffaar do not give people the freedom to cross a red light, how can we give freedom to people to leave Islaam and disbelieve in Allaah when they want to?" - Sheikh Muhammed Salih Al-Munajjid
