As often is the case, you are throwing the baby out with the bath water. I'm fairly certain no one is suggesting looking up the instructions on dam building in the Qur'an. But do these economic texts also come with instructions on how to deal with the ethical dilemmas that ensue? Like environmental issues and relocating and recompensing the local populace justly and fairly? This is a forum on Islam, why the surprise that religious issues are discussed?
