They didn't practice Islam at the same time. Once Islam spread, they converted. They also kept some distinctive touches from their traditional religions though. <span>They did not start as Muslims since Islam had not reached them yet. They only converted to Islam because they were convinced it was correct (Which in my opinion, is a correct religion). They kept a couple touches of their original religion out of loyalty to their history, culture, and those Ghanians who had not converted to Islam.</span>
This is a personal opinion but long story short, remind them about common interest of their dislike to the opponent. Talk about their differences. Make them realize they ate stronger together.
