Musannaf Ibn Abi Shaybah 20499 — What is mentioned on the virtue

Yazid bin Shajarah (may Allah have mercy on him) said: Swords are the keys of Paradise. When a man advances towards the enemy, the angels say: "O Allah! Help him." If he steps back, the angels say: "O Allah! Forgive him." As soon as the first drop of blood falls from the wound of a sword blow, all his sins are forgiven. Two maidens descend to him from Paradise, wipe the dust from his face and say: "The time has come for you." He says to them: "The time has come for you two."
