Sahih Bukhari | Volume 7 | Hadith Number 493
Narrated by Ibn 'Umar
'Umar delivered a sermon on the pulpit of Allah's Apostle, saying, "Alcoholic drinks were prohibited by Divine Order, and these drinks used to be prepared from five things, i.e., grapes, dates, wheat, barley and honey. Alcoholic drink is that, that disturbs the mind." 'Umar added, "I wish Allah's Apostle had not left us before he had given us definite verdicts concerning three matters, i.e., how much a grandfather may inherit (of his grandson), the inheritance of Al-Kalala (the deceased person among whose heirs there is no father or son), and various types of Riba(1) (usury)."
