حَدَّثَنَا هَاشِمُ بْنُ الْقَاسِمِ، حَدَّثَنَا عِكْرِمَةُ يَعْنِي ابْنَ عَمَّارٍ، حَدَّثَنِي سِمَاكٌ الْحَنَفِيُّ أَبُو زُمَيْلٍ، قَالَ: حَدَّثَنِي عَبْدُ اللَّهِ بْنُ عَبَّاسٍ، حَدَّثَنِي عُمَرُ بْنُ الْخَطَّابِ
رَضِيَ اللَّهُ عَنْهُ قَالَ لَمَّا كَانَ يَوْمُ خَيْبَرَ أَقْبَلَ نَفَرٌ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالُوا فُلَانٌ شَهِيدٌ فُلَانٌ شَهِيدٌ حَتَّى مَرُّوا عَلَى رَجُلٍ فَقَالُوا فُلَانٌ شَهِيدٌ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَلَّا إِنِّي رَأَيْتُهُ فِي النَّارِ فِي بُرْدَةٍ غَلَّهَا أَوْ عَبَاءَةٍ ثُمَّ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «يَا ابْنَ الْخَطَّابِ اذْهَبْ فَنَادِ فِي النَّاسِ أَنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا الْمُؤْمِنُونَ قَالَ فَخَرَجْتُ فَنَادَيْتُ أَلَا إِنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا الْمُؤْمِنُونَ»
Umar ibn al-Khattab told me: On the day of Khaibar, a group of the companions of the Prophet (sallallahu alayhi wa sallam) 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 (sallallahu alayhi wa sallam) said: “No, I saw him in the Fire because of a cloak or ‘abaah that he stole from the war booty.’
Then the Messenger of Allah (sallallahu alayhi wa sallam) 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.’”
