It is narrated on the authority of Umar bin Khattab that when it was the day of Khaibar a party of Companions of the Apostle ﷺ came there and said: So and so is a martyr, till they happened to pass by a man and said: So and so is a martyr. Upon this the Messenger of Allah ﷺ remarked: Nay, not so verily I have seen him in the Fire for the garment or cloak that he had stolen from the booty, Then the Messenger of Allah ﷺ said: Umar son of Khattab, go and announce to the people that none but the believers shall enter Paradise. He (Umar bin Khattab) narrated: I went out and proclaimed: Verily none but the believers would enter Paradise.
