In the opening section of Hujwiri's Kashf al-Mahjub on wearing the patched frock (lubs al-muraqqa'at), the author establishes the patched woolen garment as the distinctive emblem (shi'ar) of the Sufis and its wearing as a prophetic sunnah. He grounds this claim in several Prophetic traditions: the command to wear wool so as to find the sweetness of faith in the heart, the report that the Prophet wore wool and rode a donkey, and his instruction to Aisha not to discard a garment but to patch it (raqʿa). The muraqqa' thereby becomes a badge of voluntary poverty and humility, turning the mending of worn cloth into an outward sign of the ascetic path. As the earliest Persian prose treatise on Sufism, this treatment provides the doctrinal foundation on which later poetic allegories of the patched cloak build.
