The story of a huge blessing of Allah that favors the wealth of the world is very low.

One day, the caliph Harun-Ara-Rasid asked for water near Khadem at the throats of thirst. At that time a famous Buzurg person was near the Khadem. When the caliph wanted to drink water, he said,
Stop a little. I have a question, the caliph was a little surprised and dropped the pot. The Buzurg person said, now you want to spend a lot of water for a pot of water at the time of thirsty water?
The Khalifa thought a little bit and then said, if the thirst is more intense then this pot will give me the whole kingdom for water.

Buzurg said, drink it, after drinking water in the Khalifa, Buzurg asked the caliph permission to ask the caliph again, then Buzurg said that if the water that you drink water gets stuck in your body then you will agree to spend the amount of wealth ? The caliph said that such kind of pain would give Tharak my whole kingdom if needed for liberation.

Then Buzurg said, then what is the value of this kingdom which is to be sacrificed for drinking water or to remove one pot from the body. This water is very big like that of Allah, because of this great kingdom you have to face.
