Musnad Ahmad 32:1891

'Affan narrated to us, Marhum narrated to us, he said: I heard Thabit saying: I was sitting with Anas, and he had a daughter of his with him. Anas said: "A woman came to the Prophet, may Allah bless him and grant him peace, and said: 'O Prophet of Allah, do you have any need?'" His daughter said: "How little was her modesty!" He said: "She is better than you. She desired the Messenger of Allah, may Allah bless him and grant him peace, and offered herself to him."
