question #3 Sahih al-Bukhari 5588, Book 74, Hadith 14 : What are some unresolved issues related to inheritance and usury that were highlighted by Umar?

`Umar delivered a sermon on the pulpit of Allah’s Messenger (ﷺ), 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) .”
