It was narrated from Ma"dari bin Abi Talhah al-Ya"rnari that
"Umar stood up to deliver a khutbah. He praised and glorified Allah, then he mentioned the Prophet (ﷺ) of Allah and Abu Bakr, then he said: "I have seen a dream, in which I saw myself being pecked by a rooster twice, and I think it signals my death. The people are telling me to appoint a caliph after me. Allah will not cause His caliphate or His religion to be lost, or that with which He sent His Prophet (ﷺ). If I die, then the caliphate is to be decided by a council of these six men with whom the Messenger of Allah (ﷺ) was pleased when he died, then whichever of them you swear allegiance to, listen to him and obey. I know that there are some men then who will seek to undermine this matter, and I have sought them with these two hands of mine in support of Islam. It they do that, then those are the enemies of Allah, the misguided disbelievers. By Allah, I am not leaving behind anything of more concern to me than kalalah. I asked the Prophet (ﷺ) of Allah about it and he never spoke to me in such a harsh manner as he did with regard to that, to such an extent that he poked me in the chest or side with his hand or his finger and said: "O "Umar: The verse at the end of Soorah an Nisa’ that was revealed in summer is sufficient for you.” If I live, I will pass a judgement concerning it that no one who reads Qur"an or who does not read Qur"an will dispute. Then "Umar said: O Allah, bear witness concerning the governors of the regions; I sent them to teach the people their religion and the Sunnah of their Prophet (ﷺ), and to divide the sai" among them, and to judge between them on a fair basis, and whatever they found difficult they were to refer to me. Then he said: O people, you eat two plants that I think are nothing but distasteful, this garlic and onion. At the time of the Messenger of Allah (ﷺ), I would see that is the smell of these things was found on a man, he would be taken by the hand and led out to al-Baqee". Whoever must eat them, let him cook them to death.ʻUmar said this in a khutbah on Friday, and was stabbed on Wednesday 26 Dhul Hijjah.
