Muwatta Malik 1838

وَحَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ يَقْتَسِمُ وَرَثَتِي دَنَانِيرَ مَا تَرَكْتُ بَعْدَ نَفَقَةِ نِسَائِي وَمُؤْنَةِ عَامِلِي فَهُوَ صَدَقَةٌ ‏"‏ ‏.‏

Malik related to me from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, "My inheritance is not divided up by the dinar. What I leave apart from the maintenance of my wives and provision for my servant is sadaqa
