Al-Samawʾal ibn Yaḥyā al-Maghribī (Arabic: السموأل بن يحيى المغربي,
c. 1130 – c. 1180), commonly known as Samau'al al-Maghribi, was a
mathematician, astronomer and physician. Born to a Jewish family, he concealed
his conversion to Islam for many years in fear of offending his father, then
openly embraced Islam in 1163 after he had a dream telling him to do so. His
father was a Rabbi from Morocco.
Mathematics
Al-Samaw'al wrote the mathematical treatise al-Bahir
fi'l-jabr, meaning "The brilliant in algebra", at the age of
nineteen.
He also used the two basic concepts of mathematical
induction, though without stating them explicitly. He used this to extend
results for the binomial theorem up to n = 12 and Pascal's triangle previously
given by al-Karaji.
Polemics

Jew of Morocco.
