I decide between you on the basis of my opinion in cases about which no revelation has been sent down to me.
Sunan Abi Dawud Book 25, Hadith 15
← Previous Hadith Two men came to the Messenger of Allah (ﷺ) who were disputing over their inheritance. They had no evidence except their claim. The Prophet (ﷺ) then said in a similar way. Thereupon both the men wept and each of them said: This right of mine go to you. The Prophet (ﷺ) then said: Now you have done whatever you have done ; do divide it up, aiming at what is right, then drew lots, and let each of you consider the other to have what is legitimately his"

Sunan Abi Dawud Book 25, Hadith 14 Next Hadith → Umar said while he was (sitting) on the pulpit: O people, the opinion from the Messenger of Allah (ﷺ) was right, because Allah showed (i.e. inspired) him; but from us it is sheer conjecture and artifice.
