Abu al-Hassan Ali ibn Muhammad Al-Qayrawani Al-Rab'i[1] Al-Lakhmi (Arabic: أبو الحسن علي بن محمد القيرواني الربعي اللخمي), also known as Imam al-Lakhmi (c. 1006 – 1085 CE) (390 AH – 478 AH ), was a famous jurist in the Maliki school of Sunni Islamic Law.

Al-Lakhmi was born in Qayrawan and spent the early part of his life there before moving to Sfax.

Al-Lakhmi's juristic compendium al-Tabsirah[4] is an important text in the Maliki legal school.

It is a commentary on one of the Maliki school's most famous works, al-Mudawwana, by Sahnun b. Sa'id (d. 240/854).

In the book he discusses many questions in detail and develops opinions, relating these to teachings of other Maliki scholars.
