Muḥammad ibn Umayl al-Tamīmī was an 11th-century alchemist. One of his surviving works is Kitāb al-māʿ al-waraqī wa-l-arḍ al-najmiyya (The Book on Silvered Water and Starry Earth.) This work is a commentary on his poem Risālat al-shams wa-t-hilāl (The Epistle on the Sun and the Crescent) and contains numerous quotations from ancient authors.

.) According to Jābir, in each metal two of these qualities were interior and two were exterior. For example, lead was externally cold and dry but internally hot and moist; gold, on the other hand, was externally hot and moist but internally cold and dry. He believed that metals were formed in the Earth by fusion of sulfur

 (giving the cold and moist.) These elements, mercury and sulfur, should be thought of as not the ordinary elements but ideal, hypothetical substances. Which metal is formed depends on the purity of the mercury and sulfur and the proportion in which they come together. The later alchemist al-Rāzī followed Jābir's mercury-sulfur theory, but added a third, salty, component.

Thus, Jābir theorized, by rearranging the qualities of one metal, a different metal would result. By this reasoning, the search for the philosopher's stone
Philosopher's stone
