Sahih (Sahih Muslim)
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَقْتَسِمُ وَرَثَتِي دِيِنَارًا مَا تَرَكْتُ بَعْدَ نَفَقَةِ نِسَائِي وَمَئُونَةِ عَامِلِي فَهُوَ صَدَقَةٌ " .
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 maintenance allowance to my wives and remuneration to my manager is (to go in) charity
