Sahih Bukhari Volume 4, Book 56, Hadith 3045

حَدَّثَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه 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 ‏"

Narrated Anas bin Malik(R.A.) : Allah's Messenger (s.a.w.) entered(Makkah) in the year of the Conquest (of Makkah) wearing a helmet over his head.After he took it off, a man came and said,"Ibn Khatal is clinging to the curtains of the kabah."The Prophet(s.a.w.) said,"Kill him."
