Narrated 'Amir bin Al-Harith:
حَدَّثَنَا قُتَيْبَةُ ، حَدَّثَنَا أَبُو الأَحْوَصِ ، عَنْ أَبِي إِسْحَاقَ ، عَنْ عَمْرِو بْنِ الْحَارِثِ ، قَالَ مَا تَرَكَ رَسُولُ اللَّهِ صلى الله عليه وسلم دِينَارًا وَلاَ دِرْهَمًا وَلاَ عَبْدًا وَلاَ أَمَةً، إِلاَّ بَغْلَتَهُ الْبَيْضَاءَ الَّتِي كَانَ يَرْكَبُهَا، وَسِلاَحَهُ، وَأَرْضًا جَعَلَهَا لاِبْنِ السَّبِيلِ صَدَقَةً.
Allah's Messenger (ﷺ) did not leave a Dinar or a Dirham or a male or a female slave. He left only his white mule on which he used to ride, and his weapons, and a piece of land which he gave in charity for the needy travelers.
