Musnad Ahmad 1153:104

Sufyan narrated to us, from Abd al-Rahman ibn al-Qasim, from his father, from Aisha: Safiyyah menstruated, so she mentioned that to the Messenger of Allah, peace and blessings of Allah be upon him. He said, "Is she going to detain us?" I said, "She has already performed the Ifadah (Tawaf al-Ifadah) before that." He said, "Then no."
