The texts
٣٨١ - مَسْأَلَةٌ: وَلَا يَحِلُّ لِلْمُصَلِّي أَنْ يَضُمَّ ثِيَابَهُ أَوْ يَجْمَعَ شَعْرَهُ قَاصِدًا بِذَلِكَ لِلصَّلَاةِ، لِقَوْلِ رَسُولِ اللَّهِ - صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ - الَّذِي قَدْ ذَكَرْنَاهُ بِإِسْنَادِهِ «أُمِرْتُ أَنْ أَسْجُدَ عَلَى سَبْعَةِ أَعْظُمَ وَأَنْ لَا أَكْفِتَ شَعْرًا وَلَا ثَوْبًا» . [مَسْأَلَةٌ عَلَى الْمُصَلِّي أَنْ يَغُضَّ بَصَرَهُ عَنْ كُلِّ مَا لَا يَحِلُّ لَهُ النَّظَرُ إلَيْهِ]
