Narrated Anas bin Malik:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، أَخْبَرَنَا مَالِكٌ ، عَنِ ابْنِ شِهَابٍ ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم دَخَلَ عَامَ الْفَتْحِ، وَعَلَى رَأْسِهِ الْمِغْفَرُ، فَلَمَّا نَزَعَهُ جَاءَ رَجُلٌ، فَقَالَ إِنَّ ابْنَ خَطَلٍ مُتَعَلِّقٌ بِأَسْتَارِ الْكَعْبَةِ. فَقَالَ " اقْتُلُوهُ " .
Allah's Messenger (ﷺ) entered Mecca in the year of its Conquest wearing an Arabian helmet on his head and when the Prophet (ﷺ) took it off, a person came and said, "Ibn Khatal is holding the covering of the Ka`ba (taking refuge in the Ka`ba)." The Prophet (ﷺ) said, "Kill him."
