Abu Hamzah (may Allah have mercy on him) narrates: I used to keep people away from Sayyiduna Ibn Abbas (may Allah be pleased with them both). Once, I could not go for a few days. Later, when I went, he said: What kept you from coming to me? I said: I was afflicted with fever. He said: Indeed, the Noble Prophet (peace and blessings be upon him) said: Fever is from the steam of Hellfire, so cool it with the water of Zamzam.
