Invest in yourself by learning how to help others and help yourself.
Abu Hurayrah narrated: While a man was in the wilderness, he heard a voice from a cloud, commanding: “Irrigate the garden of so-and-so.” After that, the clouds slinked aside and poured water on a stony ground. The water filled a channel amongst the channels of the land, and that man followed the flow of the water until he found another man standing in a garden who was busy with changing the course of the water with a tool. The first man said to the second, “Oh slave of Allah, what is your name?” The second man responded, “So-and-so.” And this was the very same name the first man had heard from the clouds. The second man asked, “Oh slave of Allah, why do you ask me my name?” The first man responded, “I heard a voice from the clouds, from which this downpour originated, saying, ‘Water the garden of so-and-so’, like your name. What do you do for the favor of Allah to be shown to you in this matter?” The second man said, “Now as you see. I look at the yield I get from the land, and I give one-third as charity out of it, I and my children eat one-third of it, and the remaining third I return to it as an investment.” – as narrated in Sahih Muslim (42: 7112)
