Plant a tree

Yesterday, I came across this hadith:
"Even if you see qiamah is about to happen, still go ahead and plant the tree in your hand"
(I want to find the original Arabic so that we can smooth out the language.)

This hadith puts effort in perspective. What really matters is not the result, but the deed. And it's difficult to think like that, because we want to see results. I work hard in my teaching, and when I don't see the results, it's very discouraging, it's very difficult to go on and do the right thing when the right thing doesn't bring in results right away.

It's all about courage. My English 9th class the other day was discussing this quote by Atticus in To Kill a Mockingbird:
I wanted you to see what real courage is, instead of getting the idea that courage is a man with a gun in his hand. It's when you know you're licked before you begin but you begin anyway and you see it through no matter what. You rarely win, but sometimes you do. ~Atticus, Chapter 11
