Messenger of Allah 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.  

مَا تَرَكَ رَسُولُ اللَّهِ ﷺ دِينَارًا وَلاَ دِرْهَمًا وَلاَ عَبْدًا وَلاَ أَمَةً إِلاَّ بَغْلَتَهُ الْبَيْضَاءَ الَّتِي كَانَ يَرْكَبُهَا وَسِلاَحَهُ وَأَرْضًا جَعَلَهَا لاِبْنِ السَّبِيلِ صَدَقَةً  

[Machine] "And by Allah, the Messenger of Allah ﷺ did not leave behind at his death a dinar or a dirham, nor a slave nor a female slave, except for his mule and weapons, and a piece of land that he left as charity."  

«وَاللَّهِ مَا تَرَكَ رَسُولُ اللَّهِ ﷺ عِنْدَ مَوْتِهِ دِينَارًا وَلَا دِرْهَمًا وَلَا عَبْدًا وَلَا أَمَةً إِلَّا بَغْلَتَهُ وَسِلَاحَهُ وَأَرْضًا تَرَكَهَا صَدَقَةً»  

"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." (Using translation from Nasāʾī 3594)  

«مَا تَرَكَ رَسُولُ اللهِ ﷺ دِينَارًا وَلَا دِرْهَمًا وَلَا عَبْدًا وَلَا أَمَةً إِلَّا بَغْلَتَهُ الشَّهْبَاءَ الَّتِي كَانَ يَرْكَبُهَا وَسِلَاحَهُ وَأَرْضًا جَعَلَهَا فِي سَبِيلِ اللهِ» وَقَالَ قُتَيْبَةُ مَرَّةً أُخْرَى «صَدَقَةً»
