Musannaf Ibn Abi Shaybah 25277 — The water of the Euphrates

It is narrated from Qays bin Abi Hazim, who said: A man fell ill at al-Mada'in. The narrator said: I think he was a hypocrite. Sayyiduna Hudhayfah (may Allah be pleased with him) said: Take this man to the water of the Euphrates, for the water of the Euphrates is lighter than the water of the Tigris. The narrator said: So the man was taken there, and he died.
