`Umar bin al-Khattab (s) said: On the day of Khaibar, a group of the companions of the Messenger of Allah (ﷺ) said: So and so is a martyr, So and so is a martyr, until they passed by a man and said: So and so is a martyr. The Messenger of Allah (ﷺ) said: `No, I saw him being dragged to Hell because of a cloak that he stole from the booty. Go out and call out to the people, “No one will enter Paradise except the believers.` So I went out and called out: No one will enter Paradise except the believers.
