Sahih al-Bukhari, Volume 4, Book 52, Hadith 125 (USC-MSA) ⓘ
Narrated `Amr bin Al-Harith: The Prophet did not leave anything behind him after his death except a white mule, his arms and a piece of land which he left to be given in charity.
حَدَّثَنَا عَمْرُو بْنُ عَلِيٍّ، حَدَّثَنَا يَحْيَى، حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنِي أَبُو إِسْحَاقَ، قَالَ سَمِعْتُ عَمْرَو بْنَ الْحَارِثِ، قَالَ مَا تَرَكَ النَّبِيُّ صلى الله عليه وسلم إِلاَّ بَغْلَتَهُ الْبَيْضَاءَ وَسِلاَحَهُ وَأَرْضًا تَرَكَهَا صَدَقَةً.
