Mishkat al-Masabih 1464

Jabir told of God’s messenger visiting Umm as-Saib (Ibn Abd al-Barr (Istiab, p. 781) gives her name in this form, but says she is called by some Umm al-Musayyib) and asking, “What is the matter with you that you are trembling?” She replied, “Fever; may God not bless it.” He said, “Do not revile fever, for it removes the sins of the sons of Adam just as the bellows remove the dross of iron.”
