عَنْ أَبِي بَكْرِ بْنِ عَبْدِ اللَّهِ بْنِ قَيْسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعْتُ أَبِي وَهُوَ بِحَضْرَةِ الْعَدُوِّ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ إِنَّ أَبْوَابَ الْجَنَّةِ تَحْتَ ظِلَالِ السُّيُوفِ قَالَ فَقَامَ رَجُلٌ مِنَ الْقَوْمِ رَثُّ الْهَيْئَةِ فَقَالَ يَا أَبَا مُوسَى أَأَنْتَ سَمِعْتَ هَذَا مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ نَعَمْ قَالَ فَرَجَعَ إِلَى أَصْحَابِهِ فَقَالَ أَقْرَأُ عَلَيْكُمُ السَّلَامَ ثُمَّ كَسَرَ جَفْنَ سَيْفِهِ فَأَلْقَاهُ ثُمَّ مَشَى بِسَيْفِهِ فَضَرَبَ بِهِ حَتَّى قُتِلَ
Abu Bakr bin Abdullah says: In the presence of the enemies, I heard my father saying: I heard the Messenger of Allah, peace and blessings be upon him, saying: The gates of Paradise are under the shadows of swords. A disheveled man stood up and said: O Abu Musa! Did you hear this hadith from the Messenger of Allah, peace and blessings be upon him? He said: Yes. Then he returned to his companions and said: I bid you all peace, then he broke the sheath of his sword and threw it away, took his sword and set out, and began to strike the enemies with it, until he himself was martyred.
