In Islamic culture, two angels from heaven - Harut and Marut - descended down to Earth upon the orders of Allah, and gave magical instructions to Mankind, consisting of medical cures, drugs, musical instruments, as well as advanced cosmetic arts; these instructions were given 'as a test' (in Islam it's never explained why there are these 'tests' or what their purpose might really be since Allah already knows everything and presumably He does not need to test anything for Himself...).
