The Book on Jihad — Hadith #1693
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ دَخَلَ النَّبِيُّ صلى الله عليه وسلم عَامَ الْفَتْحِ وَعَلَى رَأْسِهِ الْمِغْفَرُ فَقِيلَ لَهُ ابْنُ خَطَلٍ مُتَعَلِّقٌ بِأَسْتَارِ الْكَعْبَةِ . فَقَالَ
" اقْتُلُوهُ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ لاَ نَعْرِفُ كَبِيرَ أَحَدٍ رَوَاهُ غَيْرَ مَالِكٍ عَنِ الزُّهْرِيِّ .
The Prophet (ﷺ) entered (Makkah) during they year of the Conquest, and upon his head was a helmet (Mighfar). It was said to him: ‘Ibn Khatal is clinging to the covering of the Ka’bah.’ So he said: ‘Kill him.'”
This Hadith is Hasan Sahih Gharib. We do knot know of anyone important who reported it other than Malik from Az-Zuhri.
