He granted me as a nafal a slave girl from Banu Fazarah, who was the most beautiful of the Arabs, and she was wearing her old garment. I did not uncover any of her clothing until I came to Medina. The Prophet (peace be upon him) met me in the marketplace and said: "May your father be ransomed for you, give her to me." So I gave her to him, and he sent her to ransom some prisoners of the Muslims who were in Mecca. (2)

When the two lines meet, or he said: The two armies, then it is a spoil.
