Sahih al-Bukhari 2912Book 56, Hadith 125
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.
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 .
