مسند أحمد

Abdullah bin ‘Abbas said: Umar bin al-Khattab told me: On the day of Khaibar, a group of the companions of the Prophet (ﷺ) 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) 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.”
