Musnad Ahmad 32:837

Muhammad ibn Ja’far and Hajjaj narrated to us, they said: Shu’bah narrated to us. Ibn Ja’far said in his narration: He said: I heard Ali ibn Zayd say: Anas ibn Malik said: "If a slave girl from the slave girls of the people of Medina were to come and take the hand of the Messenger of Allah, may Allah bless him and grant him peace, he would not pull his hand away from her hand until she had taken him wherever she wished."
