Messenger of Allah ﷺ said, "My heirs should not take even a single Dinar (i.e. anything from my property), and whatever I leave, excluding the expenditure of my wives and my laborers, will be Sadaqa (i.e. be used for charity)."'  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَقْتَسِمُ وَرَثَتِي دِينَارًا مَا تَرَكْتُ بَعْدَ نَفَقَةِ نِسَائِي وَمَئُونَةِ عَامِلِي فَهْوَ صَدَقَةٌ  

Messenger of Allah ﷺ died, and there was nothing in my house that a living being could eat, except some barley Lying on a shelf. So, I ate of it for a long period and measured it, and (after a short period) it was consumed.  

تُوُفِّيَ رَسُولُ اللَّهِ ﷺ وَمَا فِي بَيْتِي مِنْ شَىْءٍ يَأْكُلُهُ ذُو كَبِدٍ إِلاَّ شَطْرُ شَعِيرٍ فِي رَفٍّ لِي فَأَكَلْتُ مِنْهُ حَتَّى طَالَ عَلَىَّ فَكِلْتُهُ فَفَنِيَ  

The Prophet ﷺ did not leave anything (after his death) except his arms, a white mule, and a (piece of) land which he had given as Sadaqa.  

مَا تَرَكَ النَّبِيُّ ﷺ إِلاَّ سِلاَحَهُ وَبَغْلَتَهُ الْبَيْضَاءَ وَأَرْضًا تَرَكَهَا صَدَقَةً
