In the evening of that day — i.e. Saturday, the seventh of Shawwal, 3rd year A.H. — the Messenger arrived in Madinah. As soon as he reached his house, he handed his sword to his daughter Fatimah and said: "O daughter, wash the blood off this sword. By Allâh it has been helpful to me today." ‘Ali bin Abi Talib handed her his sword and said: "And wash the blood of this sword too. By Allâh, it has been helpful to me today." So the Messenger of Allâh [pbuh] said: "Sahl bin Haneef and Abu Dujana have been as courageous as you are in the fight." [Ibn Hisham 2/100]
