He benefited from the works of his teacher, Sened bin Ali, in his studies in the field of astronomy.

Abu Ma’şer lived at the same time as the great scholar Bettânî. His works had a profound impact on the development of astronomy and mathematics in Europe. The famous calculation method, which is named after him, has been the main application point in the field of astronomy for centuries.

Abu Ma’şer, who discovered the tide event for the first time, explained its nature and its relationship with the moon. This information was later transferred to European scientific circles. Philip K. Hitti, one of the researchers in the history of science: “Ebû Ma’şer, who taught the principles and laws of the tide event to Europe and put forward the theory in this field for the first time.” says.

Abu Ma’şer also put forward ideas about latitude degrees and lengths. His explanations on both the tide and the calculation of latitude degrees guided Europe in astronomical geography.
