Abu ‘Atab and al-Husayn, the sons of Bistam, narrated from Muhammad b. Khalaf from ‘Umar b. Thuwayh from his father from al-Sadiq, peace be upon him, that a man complained to him [al-Sadiq] of whiteness in the eyes (bayad al-‘ayn), pain in his teeth, and wind in his joints. He instructed him to take the weight of two dirhams each of white pepper and long pepper and the weight of one dirham of good, pure salammoniac (nushadir). Grind and sieve them, and apply three strokes around the edges of each eye. Keep it on for an hour. It will put an end to the whiteness, purify the white of the eye, and ease the pain, Allah, the Exalted, willing. Then wash the eyes with cold water and apply antimony.
Ahmad h. Habib narrated from al -Nadr b. Suwayd from Jamil b. Salih from Dharih, who said: A man complained to Abu Ja’far al-Baqir, peace be upon him, of whiteness in the eyes. He [al-Baqir] said: “Take one part each of impure oxide of zinc, (tutiya hindi), scoria of gold (iqlimiya al-dhahab), good quality antimony, yellow myrobalan, and andarani salt [salt evaporated from sea water]. Grind each one separately with rainwater. Then grind them together and apply around the eyes. It will put an end to the whiteness, clear the white of the eye, and purify it of every illness, Allah, the Mighty and Sublime, willing.”
Al-Hasan b. Aruma narrated from ‘Abd Allah b. al-Mughira from Buzigh al-Mu'adhdhin, who said: I said to Abu ‘Abd Allah, peace be upon him, “I wish to remove my cataract.” He said: “Ask Allah and do it.” I said: “They claim that the person should sleep on his back in such-and-such a way, and should not pray sitting down.” He said: “Do that.”
