REWARD OF THEFT H H 217 "On the day of the battle of Khybar, a group of the Companions of the Prophet, praise and peace be upon him, came saying: 'So and so has become a martyr, so and so has become a martyr.' Then they passed by a corpse and remarked: 'He is also a martyr.' The Prophet, praise and peace be upon him, said: 'Indeed no, I have seen him in the Fire in a cloak he stole.'" R 217 Muslim with a chain up to Omar son of Khattab who related this.
216- وعن عمر بن الخطاب رضي الله عنه ، قَالَ : لَمَّا كَانَ يَوْمُ خَيبَر أقْبَلَ نَفَرٌ مِنْ أصْحَابِ النَّبيِّ صلى الله عليه وآله وسلم ، فقَالُوا : فُلاَنٌ شَهِيدٌ ، وفُلانٌ شَهِيدٌ ، حَتَّى مَرُّوا عَلَى رَجُلٍ ، فقالوا : فُلانٌ شَهِيدٌ . فَقَالَ النَّبيُّ صلى الله عليه وآله وسلم : "كَلاَّ ، إنِّي رَأيْتُهُ في النَّار في بُرْدَةٍ غَلَّهَا - أَوْ عَبَاءة -" رواه مسلم .
