The book “Sharh Ibn Aqil” in Syntax is a commentary written by Ibn Aqil on the book, ‘Alfiyyah’ of Ibn Malik. It is a complete review of Syntax and resembles ‘Al-Bahjat al-Mardiyyah’ written by Suyouti which is also a commentary on Alfiyyah. In the Islamic Seminaries one of these two books is conventionally taught on the second level.
