His family, originally from Harran in Mesopotamia, emigrated with him to Ifriqiya. He collected his views on religious law in the Asadiyya, which had great influence in Ifriqiya. After his return to Ifriqiya he became a judge in Kairouan, where he soon came into conflict with the Aghlabid Emir Ziyadat Allah I (817-838) after criticising his luxurious and impious lifestyle.
In order to get rid of this unwelcome critic, Ziyadat appointed Asad the leader of an expedition to Byzantine Sicily. In 827 Asad landed with a force of Arabs in Sicily and following a defeat of Byzantine troops proceeded to besiege Syracuse. However, the city could not be taken and Asad soon died of plague.
Asad was prominent in establishing the Malikite Madh'hab in Ifriqiya.
