Musnad Abu Ya'la al-Mawsili 150:435

Abu Bakr ibn Abi Shaybah narrated to us, Yazid ibn al-Miqdam ibn Shurayh narrated to us, from al-Miqdam ibn Shurayh, from his father, that he mentioned that ‘A’ishah narrated to him that when she was menstruating, the Messenger of Allah (may Allah bless him and grant him peace) would say to her, "O daughter of Abu Bakr, tighten your waist-wrapper." And he would engage in physical intimacy with her during the night as much as Allah willed. And he would perform the Takbir for his prayer, and he rarely slept during the night, due to what Allah said: "Stand [to pray] the night, except for a little."
