Narrated Abu Huraira
Allah's Messenger (ﷺ) said, "My heirs will not inherit a Dinar or a Dirham (i.e. money), for whatever I leave (excluding the adequate support of my wives and the wages of my employees) is given in charity."
Narrated Ibn `Umar
When `Umar founded an endowment he stipulated that its administrator could eat from it and also feed his friend on the condition that he would not store anything for himself from it.
