Musnad Ahmad 1153:164

Yahya narrated to us, from Jabir ibn Subh, who said: I heard Khallas say: I heard Aisha say: "I used to spend the night, I and the Messenger of Allah, may Allah bless him and grant him peace, under the same garment, while I was menstruating and in a state of hayd." She said: "If anything from me touched him, he would wash it, and he would not go beyond that place, and he would pray in it. And if anything from him touched it, he would not go beyond that."
