Mishkat al-Masabih 10 The Rites of Pilgrimage كتاب المناسك 207

وَعَنْ أَنَسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَخَلَ مَكَّةَ يَوْمَ الْفَتْحِ وَعَلَى رَأْسِهِ الْمِغْفَرُ فَلَمَّا نَزَعَهُ جَاءَ رَجُلٌ وَقَالَ: إِنَّ ابْنَ خَطَلٍ مُتَعَلِّقٌ بِأَسْتَارِ الْكَعْبَةِ. فَقَالَ: «اقتله»

Anas said that the Prophet entered , Mecca on the day of the Conquest with a helmet on his head, and when he pulled it off a man came to him and said, “Ibn Khatal (He was a renegade Muslim) is hanging on to the curtains of the Ka’ba.” He replied, “Kill him.” Bukhari and Muslim.
