Hisham bin Abi 'Abdullah al-Dastawa'i هشام بن أبي عبد الله الدستوائي · The Book of Wills

"My mother has died and she had a vow to fulfill. Will it suffice if I free a slave on her behalf?" He said: "Free a slave on behalf of your mother."

"Fulfill it on her behalf."

"I am poor and I do not have anything, and I have an orphan (under my care)." He said: "Eat from the property of your orphan without being extravagant, wasteful or keeping it as capital for yourself."
