Ar-Risalah al-Qushayriyyah

الرسالة القشيرية

One of the most influential manuals of Sufism, grounding spiritual practice firmly in orthodox Sunni Islam. Al-Qushayri begins with biographies of early Sufi masters, then systematically defines key spiritual concepts (stations and states) with evidence from the Quran, Sunnah, and the practice of the righteous predecessors.
