Abu Musa reported God’s Messenger as saying, “The gates of paradise are under the shadow of the swords.” A man with a ragged appearance got up and asked Abu Musa whether he had heard God's Messenger say that; and when he received the reply that he had, he returned to his companions, said, “I salute you,” then broke the scabbard of his sword and threw it away, then went towards the enemy with his sword and plied it till he was killed. Muslim transmitted it.

وَعَنْ أَبِي مُوسَى قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ أَبْوَابَ الْجَنَّةِ تَحْتَ ظِلَالِ السُّيُوفِ» فَقَامَ رَجُلٌ رَثُّ الْهَيْئَةِ فَقَالَ: يَا أَبَا مُوسَى أَنْتَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ هَذَا؟ قَالَ: نَعَمْ فَرَجَعَ إِلَى أَصْحَابِهِ فَقَالَ: أَقْرَأُ عَلَيْكُمُ السَّلَامَ ثُمَّ كَسَرَ جَفْنَ سَيْفِهِ فَأَلْقَاهُ ثُمَّ مَشَى بِسَيْفِهِ إِلَى الْعَدُوِّ فَضَرَبَ بِهِ حَتَّى قُتِلَ. رَوَاهُ مُسلم
