Musannaf Ibn Abi Shayba 19:522

Abu Bakr narrated to us, he said: Abd al-Rahim narrated to us, from Isma'il al-Hanafi, from Umm Razin, she said: I heard Ibn Abbas saying: "Are these commanders of ours unable to cut as this Bedouin cut?" Meaning Najdah, "For he has indeed cut, and he did not miss. A man cuts and leaves its consequence."
