The Book on Government (Kitab Al-Imara)
Muslim :: Book 20 : Hadith 4728
It has been narrated on the authority of Jabir that the Messenger of Allah (may peace be upon him) said: If one of you comes (back from a journey) at night. he should not enter his house as a night visitor (but should wait) until a woman whose husband has been away from house has removed the hair from her private parts and a woman with dishevelled hair has combed her hair.
