Wealth as stewardship beyond basic needs
Nahj al-Balāgha|Volume 1|Book 3|Chapter 192
١٩٢. وَقَالَ (عليه السلام): يَا ابْنَ آدَمَ مَا كَسَبْتَ فَوْقَ قُوتِكَ، فَأَنْتَ فِيهِ خَازِنٌ لِغَيْرِكَ.
192. Amīr al-mu’minīn, peace be upon him, said: O son of Adam, whatever you earn beyond your basic needs you are only a treasurer of it for others.
