<b>Guidance from the Hadiths:</b><br> 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.<br> 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.<br> 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?
