Shari’a laws viz-a-viz natural law

While Shari’a laws are antithetical to nationalism, they project and express coherent pluralism , unity, peace , equality, mutual respect, equal opportunities,relationality, and others, one can easily, on this ground identifies them with natural law which among other things is emphasizing on the common good. However, what I don’t seem to understand is whether Shari’a laws mean different thing for different countries. This is because in some developing countries like my country, Nigeria I don’t the Muslims have really understood what the laws entail and what the law required of them. This is a place a particular will have as their “motto”, “born to rule”, this is where a Muslim president will appoint all the service chiefs from one particular tribe and religion, this where a particular section and religion in the country has had it as their birth rate to produce a president of a a supposed secular state. Given this observation one can say that Shari’a laws in principle can be said to have close sameness with natural law, but in practice project nationalistic and communistic principles. Thus the content of the code of Shari’a laws I can say is wrongly applied and as such in praxis has the interest of particular sections and religions. Hence, their assurance social order and social justice is utopian
