Musannaf Ibn Abi Shaybah 11131 — Reports on the reward for fever

It is narrated from Asim that Abu al-Aliyah went to visit al-Nadr bin Anas. He said: For fifty years we have been relating that no believing servant falls ill except that, when he recovers and gets up, he gets up as he was on the day he was born. And for fifty years we have been relating that no believing servant falls ill except that Allah Almighty says to the Noble Scribes: "Write for My servant the deeds he used to do while healthy."
