Musnad Ahmad 1153:1826

Ishaq ibn Yusuf narrated to us, he said: Sufyan informed us, from Hakim ibn Jubayr, from Sa'id ibn Jubayr, from Aisha, that she said: "I did not see the Messenger of Allah, may Allah bless him and grant him peace, [hasten] toward anything more quickly than [he did] toward the two rak'ahs before the dawn, nor toward [any] spoils of war."
