Musannaf Ibn Abi Shaybah

Hazrat Abu Ishaq narrates that once a man came to the service of the Prophet ﷺ and requested, "Give me a sword." The Prophet ﷺ said: "It should not be that I give you a sword but you stand in the back row." The Prophet ﷺ gave him the sword; he kept fighting the polytheists and at the same time recited this verse: "I am the person from whom my beloved took a promise while standing under the date trees that I will not remain standing in the back row, but rather, taking the sword of Allah and His Messenger, I will fight the enemies."
