And Ishaq ibn Mansur narrated to me, Muhammad ibn Jahdam informed us, Isma'il — who in our view is Ibn Ja'far — narrated to us, from 'Umar ibn Nafi', from his father, who said: One day 'Abdullah ibn 'Umar was at a building of his being demolished when he saw the glint of a snake. He said, "Follow this snake and kill it." Abu Lubabah al-Ansari said, "Indeed, I heard the Messenger of Allah, peace and blessings be upon him, forbid the killing of the snakes that are in houses, except the short-tailed one and the one with two white stripes on its back, for they are the ones that snatch away the eyesight and seek after what is in the wombs of women."
