The subject of this entry [Abū al-‘Abbās Sīdī Aḥmad al-Būs’īdī al-Hashtūkī, d. 1046/1636] was exceptional in his age in asceticism and piety, only wearing of the clothing of this world the very least necessary to humans, to the point that he had no more than one garment, and if he wanted to wash it he would go out to Wādī al-Zaytūn [a former watercourse on the north end of Fez] and tear his garment into two halves. He would wrap himself in one half and occupy himself with washing the other half; once it had dried he would wrap himself with it, then wash the other. Then when it had dried he would stitch the garment back together as it had been before. He only took sustenance from the seed that he sowed with his own hand on land which someone from the folk of good and religion had gifted him. He would make a round loaf of dough and place it in the fire, and content himself with that—such was his habit. He kept this up even though people sought him out from distant horizons, bringing abundant gifts and generous alms, yet he paid not attention to that, such making no impression on his mind. It is related that one of the elite of Fez was struck with a sickness which thwarted the doctors and wore out the enchanters, so someone suggested to the sick man that he pay a pious visit to the subject of this entry. So he sought him out in his room in the Miṣbāḥiyya Madrasa and described his present sickness to him. Then the shaykh took some of his flour and made a tincture for him, then commanded him to drink it. He drank, and immediately he was better. The shaykh said to him: “That which is ḥalāl is a theriac for the severest of sicknesses! When a sick person eats a bite of something ḥalāl it is as if he has been released from bondage.”
