Musnad Ahmad 161:1

'Abd al-Rahman narrated to us, Sufyan narrated to us, from Humayd al-A'raj, from Muhammad ibn Ibrahim, from Abu Salamah, from 'Abdullah ibn Rawahah, that he arrived from a journey at night. He hurried to his wife, and behold, there was a lamp in his house, and behold, there was something with his wife. So he took the sword. His wife said, "Stay away from me, stay away from me! So-and-so is combing my hair." He came to the Prophet, peace and blessings of Allah be upon him, and informed him. He (the Prophet) forbade a man from coming upon his family by night.
