The story:

When Soltan Sanjar was returning from hunting, he met a farmer working in his field. Upon the signal of the Soltan, his 

servants took the farmer away to a place and honoured him with various kinds of food and drink. The Soltan, after carrying him away, threw a sack in front of him and said, “Take as much as you can carry away from the treasury.”

The farmer thought and took a very small amount of gold in his hand. When the Soltan asked him why he didn’t take a sackful, the farmer replied, “I don’t need so much gold that I would carry it as a heavy burden now and after, but I need enough gold to help me carry out my deeds and duties efficiently.”
