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 . (Using translation from Bukhārī 2912)
«مَا تَرَكَ رَسُولُ اللهِ ﷺ إِلَّا سِلَاحَهُ وَبَغْلَتَهُ الْبَيْضَاءَ وأرْضًا جَعَلَهَا صَدَقَةً»
