«إذا قدم أحدكم ليلا فلا يأتين أهله طروقا؛ حتى تستحد المغيبة وتمتشط الشعثة»
The Prophet (peace and blessings be upon him) said:
"When one of you returns (from a journey) at night, he should not come to his family suddenly at night, so that the woman whose husband was away may remove her pubic hair and the woman with dishevelled hair may comb her hair."
