In general Islamic civilization emphasized the harmony between man and nature as seen in the traditional design of Islamic cities. Maximum use was made of natural elements and forces, and men built in harmony with, not in opposition to nature. Some of the Muslim technological feats such as dams which have survived for over a millenium, domes which can withstand earthquakes, and steel which reveals incredible metallurgical know-how, attest to the exceptional attainment of Muslims in many fields of technology. In fact it was a vastly superior technology that first impressed the Crusaders in their unsuccessful attempt to capture the Holy Land and much of this technology was brought back by the Crusaders to the rest of Europe.
"When a person dies, his works end, except for three: ongoing charity, knowledge that is benefited from, and a righteous child who prays for him."
Prophet Mohammed (PBUH)
"The best of what a man leaves behind are three: a righteous child who supplicates for him, ongoing charity the reward of which reaches him, and knowledge that is acted upon after him."
Sunan Ibn Mājah
"Every day two angels come down from Heaven and one of them says, 'O Allah! Compensate every person who spends in Your Cause,' and the other (angel) says, 'O Allah! Destroy every miser.'"
Sahih Bukhari
