It has been narrated on the authority of Abu Huraira that the Messenger of Allah ﷺ said: My heirs cannot share even a dinar (from my legacy) ;
what I leave behind after paving mtintenance allowance to my wives and remuneration to my manager is (to go in) charity.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " لاَ يَقْتَسِمُ وَرَثَتِي دِيِنَارًا مَا تَرَكْتُ بَعْدَ نَفَقَةِ نِسَائِي وَمَئُونَةِ عَامِلِي فَهُوَ صَدَقَةٌ " .
