Mukhtasar Sahih Bukhari — Hadith 1201

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "My heirs should not distribute dinars nor dirhams; whatever I leave after providing for my wives and paying the wages of the caretaker of my property, that is charity."
