Ahmed bin Harb bin Muhammad أحمد بن حرب بن محمد · The Book of Wills

"The mutual rivalry (for piling up of worldly things) diverts you, 'Until you visit the graves (i.e. till you die).' The son of Adam says: 'My wealth, my wealth,' but your wealth is what you eat and consume, or what you wear and it wears out, or what you give in charity and send on ahead (for the Hereafter).'"

"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."
