Mishkat al-Masabih
He reported the Prophet (ﷺ) as saying, “When you arrive during the night do not go in to your family till the woman whose husband has been away cleans herself and the dishevelled woman combs herself.” (Bukhari and Muslim.)
وَعَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِذَا دَخَلْتَ لَيْلًا فَلَا تَدَخُلْ عَلَى أهلك حَتَّى تستحد المغيبة وتمتشط الشعثة»
