What tree is this?

Question

I found this tree in my backyard, and I don't know what it is. The leaves are green, oval with a point on the end, are 3 inches long (along vein) and 1 inch wide, and has ridges on the edges. The tree itself has a trunk that's black on the bottom and grey on the top, is 12-15 feet tall, and has green, fuzzy pods on it. We thought it was a almond tree, but it didn't look like it on google. If you answer this please try to include a picture of it in your answer. Thanks!!
