The is the bone of contention. God"s laws did not change. Some changed God"s words to fit various political eras. God summed up and reiterated with the Quran and promised to preserve it Himself knwoing that the others will change his words. Does that answer your question. Note the Quran was written before the creation and remained with God till the time decreed by Him came about. This will also refute the claim that GOD aborgated some verses becauseSadly a woman was gang raped in Saudi Arabia, the criminals were set free their words worth twice that of a woman is the reason.
Try explaining the wisdom, as I doubt there is any.
If God rules never change, then why did Mohammad change Moses law, or Jesus???
HE did not foresee something or the other
