Jami` at-Tirmidhi, Volume 3, Book 20, Hadith 1659 (DarusSalam) ⓘ
Narrated Abu Bakr bin Abi Musa Al-Ash'ari: "I heard my father saying in the presence of the enemy: 'The Messenger of Allah said: "Indeed, the gates of Paradise are under the shadows of the swords.'" A man among the people with ragged appearance said: 'Have you heard what you mentioned from the Messenger of Allah ?' He said: 'Yes.' So he returned to his comrades and bid them Salam (farewell), broke the sheath of his sword, and began fighting with it until he was killed." [Abu 'Eisa said:] This Hadith is Sahih Gharib. We do not know it except as a narration of Ja'far bin Sulaiman [Ad-Dubai']. (One of the narrators) Abu 'Imran Al-Jawni's name is 'Abdul Malik bin Habib. As for Abu Bakr bin Abi Musa, Ahmad bin Hanbal said: "That is his name."
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا جَعْفَرُ بْنُ سُلَيْمَانَ الضُّبَعِيُّ، عَنْ أَبِي عِمْرَانَ الْجَوْنِيِّ، عَنْ أَبِي بَكْرِ بْنِ أَبِي مُوسَى الأَشْعَرِيِّ، قَالَ سَمِعْتُ أَبِي بِحَضْرَةِ الْعَدُوِّ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ أَبْوَابَ الْجَنَّةِ تَحْتَ ظِلاَلِ السُّيُوفِ " . فَقَالَ رَجُلٌ مِنَ الْقَوْمِ رَثُّ الْهَيْئَةِ أَأَنْتَ سَمِعْتَ هَذَا مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم يَذْكُرُهُ قَالَ نَعَمْ . فَرَجَعَ إِلَى أَصْحَابِهِ فَقَالَ أَقْرَأُ عَلَيْكُمُ السَّلاَمَ . وَكَسَرَ جَفْنَ سَيْفِهِ فَضَرَبَ بِهِ حَتَّى قُتِلَ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ جَعْفَرِ بْنِ سُلَيْمَانَ الضُّبَعِيِّ . وَأَبُو عِمْرَانَ الْجَوْنِيُّ اسْمُهُ عَبْدُ الْمَلِكِ بْنُ حَبِيبٍ وَأَبُو بَكْرِ بْنُ أَبِي مُوسَى قَالَ أَحْمَدُ بْنُ حَنْبَلٍ هُوَ اسْمُهُ .
