And Ishaq ibn Mansur narrated to me, saying: 'Abd al-Samad ibn 'Abd al-Warith informed us, saying: Ibrahim ibn Sa'd narrated to us, saying: Sa'd narrated to us, from his father, from Sa'd ibn Abi Waqqas, who said: "On the day of Uhud, I saw two men to the right of the Messenger of Allah, peace and blessings be upon him, and to his left, wearing white garments, fighting fiercely on his behalf as intensely as any fighting. I had never seen them before, nor after."
