[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
