Al-Samawal al-Maghribi

Al-Samawʾal ibn Yaḥyā al-Maghribī, commonly known as Samawʾal al-Maghribi, was a mathematician, astronomer and physician. Born to a Jewish family of Moroccan origin, he concealed his conversion to Islam for many years for 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 named Yehuda ibn Abūn.
