if you mean to challenge the western philosophers you should read the persian guy. i think his name is al-ghizahi. not that but close, i'm loosing my memory in my old age. or yaqin's curse is working, lol. anyway, the book is "the incoherance of philosophers." it is quite humourous and therefore very islamic. he puts forth the philosophy that all things are the will of allah, ocassionalism. he disputes the laws of nature and cause and effect. the example often given is that he states, 'fire doesn't burn the cotton, allah burns the cotton'.
what do you think paul. the christmas tsunami wasn't caused by an earthquake, but by allah?
