Mustadrak al-Hakim 552 — Sometimes he bathed before sleeping

Ghudayf bin al-Harith narrates: I said to Sayyidah Aishah (may Allah be pleased with her): "When the Messenger of Allah (peace and blessings be upon him) was in a state of janabah (major ritual impurity), would he perform the ritual bath (ghusl) at the beginning (of the night) or at the end?" She said: "Sometimes he would perform the ritual bath at the beginning, and sometimes he would perform it at the end." I said (joyfully): "Allahu Akbar! All praise is for Allah, who has made room for ease in this matter."
