Muhammad bin Ishaq (may Allah have mercy on him) relates that after the rout (on the day of Uhud) and the people's saying, "The Messenger of Allah (peace and blessings be upon him) has been killed," the first to recognise the Messenger of Allah (peace and blessings be upon him) was Sayyiduna Ka'b bin Malik (may Allah be pleased with him) (as Imam al-Zuhri (may Allah have mercy on him) narrated to me through Abdullah bin Ka'b bin Malik (may Allah have mercy on him)). Sayyiduna Ka'b bin Malik (may Allah be pleased with him) said: "I recognised his (peace and blessings be upon him) two eyes shining from beneath the helmet (the iron cap), so I called out at the top of my voice: 'O assembly of Muslims, here is the Messenger of Allah (peace and blessings be upon him)!' Then he (peace and blessings be upon him) signalled to me to keep quiet."
Only Muhammad bin Ishaq narrated this hadith from Imam al-Zuhri.
