Ahmed ibn Zayn al-Habashi’s Al-Risalah al-Jami‘ah (translated and published as The Encompassing Epistle) presents a practical introduction to the essential beliefs, practices, and moral rectifications mentioned in the Sacred Law.
The printed translation includes many notes designed to equip students for personal practice and to prepare them for more advanced studies. They are not included in this read-through, so you should equip yourself with a copy.
