Musnad Ahmad 1153:1502

'Abd al-Rahman ibn Mahdi narrated to us, he said: Shu'bah narrated to us, from Yazid al-Rishk, from Mu'adhah: That a woman asked 'A'ishah: "Does the menstruating woman make up the prayer?" She said: "Are you a Haruriyyah? The wives of the Messenger of Allah, may Allah bless him and grant him peace, used to menstruate, and he did not command them to make them up."
