Sayyiduna Anas (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "I saw in a dream as if I had a ram riding behind me, and as if the edge of my sword had broken. I interpreted it to mean that I would kill an important man of the enemy, and I interpreted the edge of my sword as a man of my family being killed." So Sayyiduna Hamzah (may Allah be pleased with him) was martyred, and the Prophet (peace and blessings be upon him) killed a man named Talhah, who was their standard-bearer.
Al-Tabarani recorded it, and these are his words; al-Bazzar and Ahmad also recorded it, but they did not record it in full. Its chain contains Ali bin Zayd, who has a poor memory; it has also been narrated through another chain, as you can see. The rest of its narrators are the narrators of the Sahih.
