Musannaf Ibn Abi Shaybah 39565 — The Battle of the Trench

Muhammad said: My father informed me from his father from Sayyidah Aishah (may Allah be pleased with her) that she said: After the Messenger of Allah (peace and blessings be upon him) and his two companions, or one of them, the loss of no one was felt more severely by the Muslims than that of Sayyiduna Sa'd bin Mu'adh (may Allah be pleased with him).
