باب تَسْتَحِدُّ الْمُغِيبَةُ وَتَمْتَشِطُ ‏{‏الشَّعِثَةُ‏}‏
Sahih al-Bukhari 5247

Narrated Jabir bin `Abdullah:

We were with the Prophet (ﷺ) in Ghazwa, and when we returned and approached Medina, I wanted to hurry while riding a slow camel. A rider overtook me and pricked my camel with a spear which he had, whereupon my camel started running as fast as any other fast camel you may see. I looked back, and behold, the rider was Allah's Messenger (ﷺ) . I said, "O Allah's Messenger (ﷺ)! I am newly married " He asked, "Have you got married?" I replied, "Yes." He said, "A virgin or a matron?" I replied, "(Not a virgin) but a matron" He said, "Why didn't you marry a young girl so that you could play with her and she with you?" When we reached (near Medina) and were going to enter it, the Prophet (ﷺ) said, "Wait till you enter your home early in the night so that the lady whose hair is unkempt may comb her hair and that the lady whose husband has been away may shave her pubic hair."

حَدَّثَنِي يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا سَيَّارٌ، عَنِ الشَّعْبِيِّ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ كُنَّا مَعَ النَّبِيِّ صلى الله عليه وسلم فِي غَزْوَةٍ، فَلَمَّا قَفَلْنَا كُنَّا قَرِيبًا مِنَ الْمَدِينَةِ تَعَجَّلْتُ عَلَى بَعِيرٍ لِي قَطُوفٍ، فَلَحِقَنِي رَاكِبٌ مِنْ خَلْفِي فَنَخَسَ بَعِيرِي بِعَنَزَةٍ كَانَتْ مَعَهُ، فَسَارَ بَعِيرِي كَأَحْسَنِ مَا أَنْتَ رَاءٍ مِنَ الإِبِلِ، فَالْتَفَتُّ فَإِذَا أَنَا بِرَسُولِ اللَّهِ صلى الله عليه وسلم فَقُلْتُ يَا رَسُولَ اللَّهِ إِنِّي حَدِيثُ عَهْدٍ بِعُرْسٍ‏.‏ قَالَ ‏"‏ أَتَزَوَّجْتَ ‏"‏‏.‏ قُلْتُ نَعَمْ‏.‏ قَالَ ‏"‏ أَبِكْرًا أَمْ ثَيِّبًا ‏"‏‏.‏ قَالَ قُلْتُ بَلْ ثَيِّبًا‏.‏ قَالَ ‏"‏ فَهَلاَّ بِكْرًا تُلاَعِبُهَا وَتُلاَعِبُكَ ‏"‏‏.‏ قَالَ فَلَمَّا قَدِمْنَا ذَهَبْنَا لِنَدْخُلَ، فَقَالَ ‏"‏ أَمْهِلُوا حَتَّى تَدْخُلُوا لَيْلاً ـ أَىْ عِشَاءً ـ لِكَىْ تَمْتَشِطَ الشَّعِثَةُ، وَتَسْتَحِدَّ الْمُغِيبَةُ ‏"‏‏.‏
