a sare assigned to allah means it is part of baitul maal from where the poor can get help. And for pea nut brains like you Prophet Muhammad died with nothing more than patched clothes, few metal objects and like. All his money and everything that could be offered was given in charity from time to time.
Despite being the head of arabia he slept ob mattress made from his own hands, leather stuffed with palm leaves, while with the war booty he could have lived like some of your gods, enjoying the dacing apsaras and light music ;)
