Majma al-Zawaid — Hadith 15166

Sufyan said: My grandmother, that is, my father's mother, related this: Two men of the Ju'fi tribe were present at the killing of Imam Husayn bin Ali (may Allah be pleased with them both). As for one of them, his private organ grew so long that he used to wrap it up; and as for the other, he would put a full waterskin to his mouth and drink it to the last drop. Sufyan said: I saw the child of one of them; he was afflicted with madness, as though he were insane.
Imam al-Tabarani recorded it, and its narrators up to Sufyan's grandmother are thiqat (trustworthy).
