As saalam Alikum,
Sister I just got married about 2 months ago to an African brother and my first husband was african as well. We always talk about pologamy in his country his father had two wife his brother and everyone its like a natural thing to do in africa. I realize they have a diffrent mind set and there wives live together and the same house. They help each other cook and take care of the children and sister its the man who keeps down the problem between the wives. It is beautiful when two wives can get along under the same roof. Thats how I reivew islam and he sunnah
