Sayyiduna Ka'b bin Malik (may Allah be pleased with him) narrates: On the day of Uhud we came towards the mountain pass, and I was the first to recognise him. I said: "This is the Messenger of Allah!" The Prophet (peace and blessings be upon him) gestured to me with his blessed hand to keep quiet. Then he put his armour on me and put on my armour himself. I fought until I received twenty wounds (the narrator is in doubt; perhaps the words are:) twenty-odd wounds, and all those wounds were inflicted because people took me to be the Messenger of Allah.
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and in al-Mu'jam al-Kabir in abridged form; the narrators of al-Mu'jam al-Awsat are thiqat (trustworthy).
