‘Ali b. Ishaq al-Basri narrated from Zakariya b. Adam al-Maqri, who used to
serve al-Rida, peace be upon him, in Khurasan, said: ‘One day al-Rida said to
me: “O Zakariya.” I answered “At your service. O son of the Messenger of Allah.”
He said: “Recite For all illness: ‘O Bestower of healing and Remover of
illness, send down healing For my ailment.’ You will be restored to health.
Allah, the Mighty and Sublime, willing.”
