Sahih Bukhari Volume 7, Book 77, Hadith 5821

حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عَبْدُ الْوَهَّابِ، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ خُبَيْبٍ، عَنْ حَفْصِ بْنِ عَاصِمٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ نَهَى النَّبِيُّ صلى الله عليه وسلم عَنِ الْمُلاَمَسَةِ، وَالْمُنَابَذَةِ، وَعَنْ صَلاَتَيْنِ بَعْدَ الْفَجْرِ حَتَّى تَرْتَفِعَ الشَّمْسُ، وَبَعْدَ الْعَصْرِ حَتَّى تَغِيبَ، وَأَنْ يَحْتَبِيَ بِالثَّوْبِ الْوَاحِدِ، لَيْسَ عَلَى فَرْجِهِ مِنْهُ شَىْءٌ بَيْنَهُ وَبَيْنَ السَّمَاءِ، وَأَنْ يَشْتَمِلَ الصَّمَّاءَ‏
