Abu Bakr bin Abdullah says that once, in front of the enemy army, I heard my father saying that I heard the Prophet Muhammad (peace be upon him) say: "The gates of Paradise are under the shade of swords." Upon hearing this, a disheveled man from among the people stood up and said, "O Abu Musa! Did you yourself hear this hadith from the Prophet Muhammad (peace be upon him)?" He replied, "Yes!" The man returned to his companions, bade them farewell for the last time, broke the sheath of his sword and threw it away, then advanced with his sword and fought with such intensity that he was eventually martyred.
