Sahih Muslim 715 w
It has been narrated on the authority of Jabir b. 'Abdullah who said:
We accompanied the Messenger of Allah (ﷺ) on an expedition. When we came (back) to Medina and were going to enter our houses, he said: Wait and enter (your houses) in the later part of the evening so that a woman with dishevelled hair may have used the comb, and a woman whose husband has been away from home may have removed the hair from her private parts.
حَدَّثَنِي إِسْمَاعِيلُ بْنُ سَالِمٍ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا سَيَّارٌ، ح وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى،
 - وَاللَّفْظُ لَهُ - حَدَّثَنَا هُشَيْمٌ، عَنْ سَيَّارٍ، عَنِ الشَّعْبِيِّ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ كُنَّا مَعَ
 رَسُولِ اللَّهِ صلى الله عليه وسلم فِي غَزَاةٍ فَلَمَّا قَدِمْنَا الْمَدِينَةَ ذَهَبْنَا لِنَدْخُلَ فَقَالَ ‏
"‏ أَمْهِلُوا
 حَتَّى نَدْخُلَ لَيْلاً - أَىْ عِشَاءً - كَىْ تَمْتَشِطَ الشَّعِثَةُ وَتَسْتَحِدَّ الْمُغِيبَةُ ‏"‏ ‏.‏
