Please do a defense of Maqasid Sharia. Draw from your own perspectives instead of using the original "founders/apologetics" to defend such an idea.
"Islam aimed only at obtaining a hearing for its message, so that anyone who might want to accept it would be free to do as he wished, while anyone who wanted to reject it could be the master of his own destiny"
Sharia isn't just criminal law. It encompasses prostration, human freedom, justice and charity for the perservation of Allah's main articles of faith for the believers. For muslim societies, an abrupt change in family lineages, traditions and modernization would mean a sign of abandonment of all things that Allah commands. Although Allah strictly sees the universe in a determinist view, muslims retain free will in Allah's world.
Why should everyone, even dhimmies and kafirs, abide by Allah's rule?
(Suggestion: You may use incompatibilist critique to expand Allah's conception of Qadar, or defend it with a rigorous account of compatibilism. Again, if you can, draw from your own perspectives, I've already read classical Maturidis and every other evil ulama filth out there.)
