Sahih Muslim Book 20, Hadith Number 4728.

Chapter : Undesirability of returning to one’s family at night (after a long absence from home).

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.
