Put oil and butter in very large skillet or casserole, which can be covered later, and heat. When butter melts, add onion and cook, stirring occasionally, until it softens, 5 - 10 min.
Add garlic, large pinch of salt and spices. Cook, stirring for about 30 sec. Add tomatoes, chickpeas, raisins and vanilla and bring to a boil. Taste and add salt as necessary. If mixture is very dry add small amount of water.
Sprinkle chicken pieces with salt and nestle into sauce. Cover, and bring to a steady simmer. Cook until chicken is very tender, 45 - 60 min. If mixture is very wet remove cover at 30 min. and finish cooking. Garnish and serve with couscous.
