Narated By Umar ibn al-Khattab : `Umar said: The prohibition of wine came down when (the Qur’anic verse) came down. It was made from five things, namely, grapes, dates, honey, wheat, barley. Wine (khamr) is what infects (khamara) the mind. There are three things I wished that the Prophet (may peace be upon him) would not leave us until he explained them fully to our satisfaction: (share of) grandfather, one who leaves no descendants or ascendants as heirs, and the details of usury.
