Majma al-Zawaid — Hadith 15785

Sayyiduna Anas (may Allah be pleased with him) narrates: Sayyiduna Thabit bin Qays bin Shammas (may Allah be pleased with him) came on the day of the Battle of Yamamah. He had spread out his shroud and applied embalming perfume, and then he said: "O Allah! I declare myself free before You of what these people have done, and I offer You my apology for what these people have done." Then he was martyred. He had a coat of armour that was stolen. A man saw him in a dream, and he said: "My armour is in a cooking pot under the stove in such-and-such a place." Then he gave that man some instructions in the dream. The people searched for the armour, found it, and carried out his instructions. (Allamah al-Haythami says:) I say: This incident is mentioned in the Sahih, but without the story of the armour.
Al-Tabarani recorded it, and its narrators are the narrators of the Sahih.
