Contentment is a wealth that never runs out.
القناعة مال لا ينفد
Al-qanā'atu mālun lā yanfad
Ali, Nahj al-Balagha, saying 57 (Subhi al-Salih edition, p. 478; saying 57 in the Abduh edition). Nahj al-Balagha is a compilation without chains of transmission by al-Sharif al-Radi (d. 1015).
Wealth runs out as it is spent.
Contentment grows as it is spent.
One who knows how to be content
does not count what is in hand as too little.
Riches are most often a matter
not of the pocket, but of the eye.
When the eye is full, the purse fills too.
