Sahih Muslim 1357
Sahih Muslim · Book 15: The Book of Pilgrimage · It is permissible to enter Makkah without Ihram
Anas b. Malik (Allah be pleased with them) reported that Allah's Apostle (ﷺ) entered Mecca in the Year of Victory with a helmet on his head; and when he took it off, a man came to him and said:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ ، وَيَحْيَى بْنُ يَحْيَى ، وَقُتَيْبَةُ بْنُ سَعِيدٍ ، أَمَّا الْقَعْنَبِيُّ فَقَالَ قَرَأْتُ عَلَى مَالِكِ بْنِ أَنَسٍ وَأَمَّا قُتَيْبَةُ فَقَالَ حَدَّثَنَا مَالِكٌ وَقَالَ يَحْيَى - وَاللَّفْظُ لَهُ - قُلْتُ لِمَالِكٍ أَحَدَّثَكَ ابْنُ شِهَابٍ عَنْ أَنَسِ بْنِ مَالِكٍ أَنَّ النَّبِيَّ صلى الله عليه وسلم دَخَلَ مَكَّةَ عَامَ الْفَتْحِ وَعَلَى رَأْسِهِ مِغْفَرٌ فَلَمَّا نَزَعَهُ جَاءَهُ رَجُلٌ فَقَالَ ابْنُ خَطَلٍ مُتَعَلِّقٌ بِأَسْتَارِ الْكَعْبَةِ . فَقَالَ " اقْتُلُوهُ " . فَقَالَ مَالِكٌ نَعَمْ .
Ibn Khatal is hanging on to the curtains of the Ka'ba, whereupon he said: Kill him. Malik (one of the narrators) attested this statement having been made.
