(23) The Book on Jihad
كتاب الجهاد عن رسول الله صلى الله عليه وسلم
(12) Chapter: What Has Been Related About The Description Of The Sword Of The Messenger Of Allah (saws)
(12) باب مَا جَاءَ فِي صِفَةِ سَيْفِ رَسُولِ اللَّهِ صلى الله عليه وسلم
Jami` at-Tirmidhi 1683 
Narrated 'Uthman bin Sa'd:

That Ibn Sirin said: "I made my sword like the sword of Samurah bin Jundab. Samurah claimed that he made his sword like the sword of the Messenger of Allah (ﷺ), and it was a Hanafiyah."

[Abu 'Eisa said:] This Hadith is Gharib, we do not know of it except through this route. Yahya bin Sa'eed Al-Qattan has criticized 'Uthman bin Sa'd the scribe, and he graded him weak due to his memory.

حَدَّثَنَا مُحَمَّدُ بْنُ شُجَاعٍ الْبَغْدَادِيُّ، حَدَّثَنَا أَبُو عُبَيْدَةَ الْحَدَّادُ، عَنْ عُثْمَانَ بْنِ سَعْدٍ، عَنِ ابْنِ سِيرِينَ، قَالَ صَنَعْتُ سَيْفِي عَلَى سَيْفِ سَمُرَةَ بْنِ جُنْدَبٍ وَزَعَمَ سَمُرَةُ أَنَّهُ صَنَعَ سَيْفَهُ عَلَى سَيْفِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَكَانَ حَنَفِيًّا ‏.‏ قَالَ أَبُو عِيسَى هَذَ حَدِيثٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ هَذَا الْوَجْهِ ‏.‏ وَقَدْ تَكَلَّمَ يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ فِي عُثْمَانَ بْنِ سَعْدٍ الْكَاتِبِ وَضَعَّفَهُ مِنْ قِبَلِ حِفْظِهِ ‏.‏
