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 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 b. Khattab) narrated: I went out and proclaimed: Verily none but the believers would enter Paradise.  

لَمَّا كَانَ يَوْمُ خَيْبَرَ أَقْبَلَ نَفَرٌ مِنْ صَحَابَةِ النَّبِيِّ ﷺ فَقَالُوا فُلاَنٌ شَهِيدٌ فُلاَنٌ شَهِيدٌ حَتَّى مَرُّوا عَلَى رَجُلٍ فَقَالُوا فُلاَنٌ شَهِيدٌ فَقَالَ رَسُولُ اللَّهِ ﷺ كَلاَّ إِنِّي رَأَيْتُهُ فِي النَّارِ فِي بُرْدَةٍ غَلَّهَا أَوْ عَبَاءَةٍ ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ يَا ابْنَ الْخَطَّابِ اذْهَبْ فَنَادِ فِي النَّاسِ إِنَّهُ لاَ يَدْخُلُ الْجَنَّةَ إِلاَّ الْمُؤْمِنُونَ قَالَ فَخَرَجْتُ فَنَادَيْتُ أَلاَ إِنَّهُ لاَ يَدْخُلُ الْجَنَّةَ إِلاَّ الْمُؤْمِنُونَ  

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: ʿNo, 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.ʿ So I went out and called out: No one will enter Paradise except the believers.  

لَمَّا كَانَ يَوْمُ خَيْبَرَ أَقْبَلَ نَفَرٌ مِنْ أَصْحَابِ رَسُولِ اللهِ ﷺ يَقُولُونَ فُلانٌ شَهِيدٌ وَفُلانٌ شَهِيدٌ حَتَّى مَرُّوا بِرَجُلٍ فَقَالُوا فُلانٌ شَهِيدٌ فَقَالَ رَسُولُ اللهِ ﷺ كَلَّا إِنِّي رَأَيْتُهُ يُجَرُّ إِلَى النَّارِ فِي عَبَاءَةٍ غَلَّهَا اخْرُجْ يَا عُمَرُ فَنَادِ فِي النَّاسِ إِنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا الْمُؤْمِنُونَ فَخَرَجْتُ فَنَادَيْتُ إِنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا الْمُؤْمِنُونَ  

Umar bin al-Khattab told me: On the day of Khaibar, a group of the companions of the Prophet 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 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: ʿNo one will enter Paradise except the believers.”  

لَمَّا كَانَ يَوْمُ خَيْبَرَ أَقْبَلَ نَفَرٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ فَقَالُوا فُلانٌ شَهِيدٌ فُلانٌ شَهِيدٌ حَتَّى مَرُّوا عَلَى رَجُلٍ فَقَالُوا فُلانٌ شَهِيدٌ فَقَالَ رَسُولُ اللهِ ﷺ كَلَّا إِنِّي رَأَيْتُهُ فِي النَّارِ فِي بُرْدَةٍ غَلَّهَا أَوْ عَبَاءَةٍ ثُمَّ قَالَ رَسُولُ اللهِ ﷺ يَا ابْنَ الْخَطَّابِ اذْهَبْ فَنَادِ فِي النَّاسِ أَنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا الْمُؤْمِنُونَ قَالَ فَخَرَجْتُفَنَادَيْتُ أَلا إِنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا الْمُؤْمِنُونَ  

[Machine] A person was killed on the day of Khaybar, and they said, "So-and-so is a martyr," until they mentioned a man. They said, "So-and-so is a martyr." Then the Messenger of Allah ﷺ said, "No, indeed I saw him in Hell, wearing a cloak or a coarse garment." Then he said to me, "O Ibn Al-Khattab, get up and announce among the people that no one will enter Paradise except the believers." So I stood up and called out to the people.  

قُتِلَ نَفَرٌ يَوْمَ خَيْبَرَ فَقَالُوا فُلَانٌ شَهِيدٌ حَتَّى ذَكَرُوا رَجُلًا فَقَالُوا فُلَانٌ شَهِيدٌ فَقَالَ رَسُولُ اللَّهِ ﷺ «كَلَّا إِنِّي رَأَيْتُهُ فِي النَّارِ فِي عَبَاءَةٍ أَوْ فِي بُرْدَةٍ غَلَّهَا» ثُمَّ قَالَ لِي يَا ابْنَ الْخَطَّابِ قُمْ فَنَادِ فِي النَّاسِ أَنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا الْمُؤْمِنُونَ فَقُمْتُ فَنَادَيْتُ فِي النَّاسِ

"عن عمر بن الخطاب - ؓ - قال: "لما كان يوم خيبر أهل بعض أصحاب النبي ﷺ فقالوا: فلان شهيدٌ، فلان شهيدٌ، حتى مروا على رجلٍ، فقالوا: فلان شهيدٌ، فقال رسول الله ﷺ : كلَّا، إني رأيته في النَّار في بردَةٍ غَلَّها أو عباءةٍ، ثم قال رسول الله ﷺ : يا بن الخطاب: أذهب فنادِ في الناس أنه لا يدخل الجنة إلا المؤمنون، فخرجت فناديت: ألا إنه لا يدخل الجنة إلا المؤمنون".
