Al-Muqaddima Al-Waghlisiyya

Al-Waghlisiyya by Imam Abu Zaid Abdul Rahman Al-Waghlisi is a very important primer in Maliki fiqh. It is a heavily referenced text, especially with its commentary by Sidi Ahmed Zarruq. It is a text covering Aqida, Fiqh (Tahara, Salah, and Sawm), and Tasawwuf. The section on Tasawwuf is very detailed and covers the sins of the outer limbs and the heart.
