Musannaf Ibn Abi Shaybah 20594 — What is mentioned on the virtue

Abu Ishaq said: Once a man came to the Prophet (peace and blessings be upon him) and said: "Give me a sword." The Prophet (peace and blessings be upon him) said: "It may be that I give you a sword and you stand in the rear rank." The Prophet (peace and blessings be upon him) gave him a sword, and he fought the polytheists while reciting this verse of poetry: "I am the one from whom my dear friend took a pledge, standing beneath the palm trees, that I would not stay in the rear rank, but would take the sword of Allah and His Messenger and fight the enemies."
