Usool as-Sunnah by Imam ibn Abi Zamaneen (399H)

Treaty on the Aqeedah and Minhaj of a 4th century imam known as Ibn Abi Zamaneen.

Very rich and interesting, you can see that the Aqeedah of the Salaf and the manhaj is the same everywhere (the imam is from Cordoba) and in every age ...

With all the accents / harakat.
