Musnad Abu Ya'la al-Mawsili 150:304

Musa narrated to us, Abd al-Wahhab narrated to us, Ayyub narrated to us, from Abd al-Rahman ibn al-Qasim, from his father, from Aisha, who said: Sawda was a large, heavy woman. She sought permission from the Messenger of Allah (may Allah bless him and grant him peace) to depart from Jam' (Muzdalifah) at night, and he granted her permission. Aisha said: "I wish I had sought permission from the Messenger of Allah (may Allah bless him and grant him peace) just as Sawda sought permission from him." Ayyub said: And Aisha would not depart except with the Imam.
