باب مَنْ لَمْ يَرَ كَسْرَ السِّلاَحِ عِنْدَ الْمَوْتِ
Sahih al-Bukhari 2912

Narrated `Amr bin Al-Harith:

The Prophet (ﷺ) did not leave behind him after his death, anything except his arms, his white mule, and a piece of land at Khaibar which he left to be given in charity .

حَدَّثَنَا عَمْرُو بْنُ عَبَّاسٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، عَنْ سُفْيَانَ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَمْرِو بْنِ الْحَارِثِ، قَالَ مَا تَرَكَ النَّبِيُّ صلى الله عليه وسلم إِلاَّ سِلاَحَهُ وَبَغْلَةً بَيْضَاءَ وَأَرْضًا جَعَلَهَا صَدَقَةً‏.‏
