Umar bin al-Khattab told me: On the day of Khaibar, a group of the companions of the Prophet ﷺ came and said: So and so has been martyred. So and so has been martyred, until they came to a man and said, So and so has been martyred, but the Messenger of Allah (ﷺ) said: “No, I saw him in the Fire because of a cloak or 'aba'ah that he stole from the war booty.” Then the Messenger of Allah ﷺ said: “O son of al-Khattab, go and call out to the people that no one will enter Paradise except the believers.” So I went out and called to them, saying: `No one will enter Paradise except the believers.”
Narrated It was narrated from Salim from his father that whilst ‘Umar bin al Khattab was addressing the people on a Friday, one of the companions of the Messenger of Allah ﷺ came in, 'Umar called out to
him:
What time is this? He said: I was busy today and I did not go back to my family when I heard the call to prayer, so I did no more than doing wudoo’. ʼUmar said: Just wudooʼ, when you know that the Messenger of Allah (ﷺ) used to enjoin ghus!?
Narrated It was narrated that Abul-Aswad ad-Deeli said:
When I came to Madinah, sickness was occurring in the city and they were dying quickly. I sat with 'Umar bin al Khattab (رضي الله عنه) and a funeral passed by, Good things were said about (the deceased) and ‘Umar (رضي الله عنه) said: It is due. Then another (funeral) passed by; good things were said about (the deceased) and he said: It is due. Then a third funeral passed by: bad things were said about the deceased and ‘Umar said: It is due. I said: What is due, O Ameer al Mu'mineen? He said: I said what the Messenger of Allah (ﷺ) said: `Any Muslim in whose favour four people testify, Allah will admit him to Paradise.` We said: Or three? He said: “Or three.` We said: Or two? He said: `Or two.” Then we did not ask him about one,
Umar bin al-Khattab told me that he heard the Messenger of Allah ﷺ say: “I shall certainly expel the Jews and Christians from the Arabian Peninsula so that I will not leave anyone but Muslims.`
