9936 Al-Biruni is a main belt asteroid. It orbits the Sun once every 5.39 years. [cite web|url = http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=9936|title = 9936 Al-Biruni (1986 PN4)|work = JPL Small-Body Database Browser]

Discovered on August 8, 1986 by Eric Elst and Violeta Ivanova at the Bulgarian National Astronomical Observatory in Smolyan, it was given the provisional designation "mp|1986 PN|4". It was later renamed "Al-Biruni" after Al-Biruni, an eleventh century Persian scientist who made important contributions to anthropology, mathematics and astronomy. [MPC 60728 "Minor Planet Center"]
