In the bottom of a 4 to 6-quart slow cooker, stir together the chickpeas, tomatoes, bell peppers, onion, golden raisins, tomato paste, water, cumin, cinnamon, paprika, and salt. Scatter the chicken pieces over the top. Cover and cook until the chicken is tender and cooked through, about 6-8 hours on low or 2-3 hours on high.
