Even though these two share the same Arabic noun: 'kafala', they actually refers to two totally different things. One refers to the migrant laborers monitoring system, while the other refers to the Islamic view of child adoption. Don't mix them up. The 'kafala' system has no relation (or share roots) with the meaning of 'kafala' in Islam. It's nothing but a name of the legislation of migrant laborers.
