Narrated Ibn 'Umar told that ‘Umar gave an address on God’s Messenger’s pulpit, saying, “The prohibition of wine has come down (Al-Qur’an, 5:90) and it comes from five things:
grapes, dates, wheat, barley and honey. Wine (khamr) is what infects (khamara) the mind.”
Ibn ‘Abbas reported the Prophet as saying, “When a man calls another a Jew give him twenty lashes, when he calls someone a mukhannath* give him twenty lashes, and kill anyone who has intercourse with a woman who is within the prohibited degress.”
Tirmidhi transmitted it, saying this is a gharib tradition.
* Mukhannaths were sexually abnormal men who imitated women. Some of them were signets.
