Musannaf Ibn Abi Shaybah 39562 — The Battle of the Trench

Muhammad said: Ash'ath bin Ishaq informed me; he said: The Messenger of Allah (peace and blessings be upon him) came to him while he was being washed. He said: Then the Messenger of Allah (peace and blessings be upon him) drew in his knees and said: "An angel came in and had no place to sit, so I made room for him." His mother was weeping and saying: "Woe to the mother of Sa'd for Sa'd, for his excellence and earnestness, after the favours and glory that were his, a leader by whom the breach was filled." The Messenger of Allah (peace and blessings be upon him) said: "All women who weep lie, except the mother of Sa'd." Muhammad said: Some of our companions said: When the Messenger of Allah (peace and blessings be upon him) went out for his funeral, some of the hypocrites said: "How light is the bier of Sa'd," or "the funeral of Sa'd!"
