In a large Dutch oven over medium high heat, heat the oil.
Add the carrots and cook, stirring frequently, 3 minutes.
Add the raisins and cook, stirring, for another 2 minutes.
Remove the carrots and raisins from the pot and set aside.
In the same pot, add the lamb and cook, until browned on all sides, about 3 minutes per side.
Add the onions and cook, stirring occasionally, until onions are caramelized. This is very important to build the layers of flavor.
Add the cumin, tomato paste and pureed tomatoes. Cook until the oil separates to the surface of the mixture.
Add 1 liter of water.
Add the salt, and bring to a boil. Cover and cook undisturbed, about 1 hour.
After about 1 hour, add the rice and gently stir to combine.
Add enough water to cover the rice by no more than 1 inch.
Cook uncovered until the rice starts to become visible. Arrange the carrots and raisins in a layer on top of the rice, followed by the chickpeas.
Lower the heat. Cover and cook undisturbed, until all the liquid has evaporated and rice is cooked and fluffy, about 30 minutes.
Spoon the rice onto a large serving platter, and arrange the lamb pieces in the center. Scatter the carrots, raisins and chick peas around the meat. Serve warm.
