How can one respond to someone who claims that Muslim scholars in worldly sciences are of no importance and that their knowledge is ancient, and that infidels are the people of authentic knowledge and progress, which encourages learning from them and traveling to their countries despite religious prohibitions?

The subject of the question has been answered previously in several fatwas addressing the Muslim's stance on Western civilization, the intellectual and scientific contributions of Muslims, the Islamic civilization's synthesis of worldly well-being and the afterlife, and the misconception of the progress of heretics and non-Muslims in worldly and applied sciences.
