[Machine] Umar was appointed in the month of Rajab in the thirteenth year and he was killed in the month of Dhul-Hijjah in the twenty-third year. He remained alive for three days after being stabbed, then he died in the end of Dhul-Hijjah. Suhaib led the funeral prayer for him, and his son Abdullah ibn Umar washed his body and shrouded him in five garments. He was buried next to the Messenger of Allah ﷺ . Umar was stabbed on Wednesday, the ninth day of the remaining days of Dhul-Hijjah. Some people say he died on that day, and his age on the day he died was what I have heard from Malik ibn Anas, who mentioned that the Prophet's ﷺ age when he died was sixty-three. Some people say it was fifty-nine, and others say it was fifty-three. Some people say it was forty-five, and his caliphate lasted for ten years, four months, and some days.
