Risala
Risala (Arabic: رسالة) is a term meaning "message" or "epistle" and is widely used in Islamic literature as the title of concise treatises or letters. The word functions as a genre indicator rather than a single work, and works titled Risala appear across disciplines such as jurisprudence (fiqh), theology (kalam), grammar, and mysticism. In many cases a Risala is intended as an introduction or teaching tool, presenting core ideas in a compact form for students or communities.
The most famous instance is al-Risāla fī ʾUṣūl al-Fiqh, commonly attributed to Imam al-Shafiʿī (c. 767–820 CE).
Beyond al-Risāla, numerous other works bearing the same title circulated in Arabic, Persian, Turkish, Urdu, and
