Musannaf Ibn Abi Shaybah 11124 — Reports on the reward for fever

Sa'id bin Wahb said: I went with Sayyiduna Salman (may Allah be pleased with him) to visit a friend of his from Kindah. He said: When Allah afflicts a believer with some hardship and then removes it from him, it becomes an expiation for his sins, and he is given the chance to make amends (with Allah) in what remains (of his life). And when Allah Almighty afflicts a sinful wrongdoer with some hardship and then grants him relief, he is like a camel whose owner ties its thigh and foreleg so that it cannot walk; it does not know why it was tied, and then it is released and it does not know why it was released.
