A man peeped into some of the apartment of the prophet (May peace be upon him). The prophet (May peace be upon him) got up taking an arrowhead or arrowheads. He said: I can still picture myself looking at the Messenger of Allah (May peace be upon him) when he was exploring to pierce him.  

أَنَّ رَجُلاً اطَّلَعَ مِنْ بَعْضِ حُجَرِ النَّبِيِّ ﷺ فَقَامَ إِلَيْهِ رَسُولُ اللَّهِ ﷺ بِمِشْقَصٍ أَوْ مَشَاقِصَ قَالَ فَكَأَنِّي أَنْظُرُ إِلَى رَسُولِ اللَّهِ ﷺ يَخْتِلُهُ لِيَطْعُنَهُ  

The Prophet ﷺ said: If anyone peeps into the house of a people without their permission and he knocks out his eye, no responsibility is incurred for his eye.  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنِ اطَّلَعَ فِي دَارِ قَوْمٍ بِغَيْرِ إِذْنِهِمْ فَفَقَأُوا عَيْنَهُ فَقَدْ هَدَرَتْ عَيْنُهُ  

The Prophet ﷺ said: When one has a look into the house, then there is no (need of) permission.  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا دَخَلَ الْبَصَرُ فَلاَ إِذْنَ  

A man came. Uthman's version has: Sa'd ibn AbuWaqqas came. He stood at the door. Uthman's version has: (He stood) facing the door. The Prophet ﷺ said to him: Away from it, (stand) this side or that side. Asking permission is meant to escape from the look of an eye.  

عُثْمَانُ سَعْدُ بْنُ أَبِي وَقَّاصٍ فَوَقَفَ عَلَى بَابِ النَّبِيِّ ﷺ يَسْتَأْذِنُ فَقَامَ عَلَى الْبَابِ قَالَ عُثْمَانُ مُسْتَقْبِلَ الْبَابِ فَقَالَ لَهُ النَّبِيُّ ﷺ هَكَذَا عَنْكَ أَوْ هَكَذَا فَإِنَّمَا الاِسْتِئْذَانُ مِنَ النَّظَرِ  

A similar tradition has also been transmitted by Talhah b. Musarrif from a man from Sa’d from the prophet (May peace be upon him) through a different chain of narrators.  

عَنِ النَّبِيِّ ﷺ
