1. My father, may Allah grant him mercy, said: We were told by Muhammed bin Yahya al-‘Attar, from Ahmad bin Muhammed, from Ibrahim ibn Ishaq, from Abdullah bin Ahmad, from Ali bin Ja’far bin Zubair, from Ja’far bin Isma’eel, from a man, from Abu Abdillah, peace be upon him, that he said: I asked him how long an ill person has fever, to which he said: Dibqa. I did not know how long dibqa is, so I asked him, and he said: Ten days. In another narration: Eleven dibqas. Dibq means morning in the speech of the Roman, by which I mean eleven mornings.
