Sunan an-Nasa'i, Volume 4, Book 29, Hadith 3624 (DarusSalam) ⓘ

It was narrated that 'Amr bin Al-Harith said: "The Messenger of Allah did not leave behind a Dinar nor a Dirham, or any slave, male or female; except his white mule which he used to ride, his weapon and some land which he left to be used for the cause of Allah." (One of the narrators) Qutaibah said on one occasion: "In charity."

أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ 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 الشَّهْبَاءَ الَّتِي كَانَ يَرْكَبُهَا وَسِلاَحَهُ وَأَرْضًا جَعَلَهَا فِي سَبِيلِ اللَّهِ ‏.‏ وَقَالَ قُتَيْبَةُ مَرَّةً أُخْرَى صَدَقَةً ‏.‏
