وَعَنْ جَابِرٍ رضى الله عنه
قَالَ: «كُنَّا مَعَ رَسُولِ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي غَزَاةٍ، فَلَمَّا قَدِمْنَا اَلْمَدِينَةَ، ذَهَبْنَا لِنَدْخُلَ. فَقَالَ: «أَمْهِلُوا حَتَّى تَدْخُلُوا لَيْلًا (يَعْنِي: عِشَاءً) لِكَيْ تَمْتَشِطَ اَلشَّعِثَةُ، وَتَسْتَحِدَّ اَلْمَغِيبَةُ»
We were with the Prophet (sallallahu alayhi wa sallam) on an expedition. Then, when we arrived at al-Madinah and were about to enter he said, “Wait so that you may enter by night – i.e. in the evening in order that the woman with disheveled hair may comb it and the woman whose husband has been away may shave her pubic hairs (getting ready for her husband).”.
