985/1 - Jābir (may Allah be pleased with him) reported that the Prophet (may Allah’s peace and blessings be upon him) said: “When one of you has been away for long, let him not come back to his family at night.”
In another version: The Messenger of Allah (may Allah’s peace and blessings be upon him) forbade that a man (returning from travel) goes home to his family at night. [Narrated by Al-Bukhāri and Muslim]
986/2 - Anas (may Allah be pleased with him) reported: The Prophet (may Allah’s peace and blessings be upon him) would not go back to his family at night (when returning from travel). He used to go home in the morning or in the evening (before dark). [Narrated by Al-Bukhāri and Muslim]

1) A traveler who was away for long is instructed not to come back to his family at night, unless he notifies them of the time of his return.
2) The wisdom behind this prohibition is what the Prophet (may Allah’s peace and blessings be upon him) said: “so that the woman with unkempt hair would comb it and the woman whose husband has been absent would shave her pubic hair.” [Narrated by Al-Bukhāri and Muslim] In other words, this gives the woman time to beautify herself for her husband, according to tradition.
3) Observing the Prophetic etiquettes brings all goodness and benefit for the believers. Look how this Prophetic instruction is meant to strengthen the affection and harmony between spouses?
