And it was narrated to me by Fadl ibn Sahl; narrated to us Yazid ibn Harun; informed us Muhammad ibn Ishaq, from Nafi' and Ubaydullah ibn Abdullah, from Ibn Umar — may Allah be pleased with them both — who said: I heard the Prophet, peace and blessings be upon him, say: "Five are there for which there is no sin in killing them, even within the Sacred Precinct." And he mentioned the like of it.
