Watt says:”The main steps in the development of the mariner’s compass seem to have been shared between the Arabs and Europeans.” Another significant contribution of Muslims in advancing seafaring skills was providing nautical charts. One of the evidences in this regard is the presence of many Arabic words in European languages in this field. According to many historians, Europeans barrowed the science of Geography from Muslims. One of the influential scientists in this regard is Idrisi (1100).
