Sahl b. Sa'd as-Sa'idi reported that a person peeped through the hole of the door of Allah's Messenger (ﷺ) and he had with him some pointed thing with which he had been adjusting (the hair of his head). Allah's Messenger (ﷺ) said to him:

9) باب تَحْرِيمِ النَّظَرِ فِي بَيْتِ غَيْرِهِ ‏‏

وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَنَّأَخْبَرَهُ أَنَّ رَجُلاً اطَّلَعَ مِنْ جُحْرٍ فِي بَابِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَمَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم مِدْرًى يُرَجِّلُ بِهِ رَأْسَهُ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏‏ ‏.‏ "‏ لَوْ أَعْلَمُ أَنَّكَ تَنْظُرُ طَعَنْتُ بِهِ فِي عَيْنِكَ إِنَّمَا جَعَلَ اللَّهُ الإِذْنَ مِنْ أَجْلِ الْبَصَرِ ‏"
