Ibn Ishaq محمد بن إسحاق بن يسار‎ · The Book on Jihad

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.
