Sayyiduna al-Sa'b bin Jaththamah (may Allah be pleased with him) said: I was at a place called al-Abwa' or Waddan when the Messenger of Allah (peace and blessings be upon him) passed by me, and I presented him (peace and blessings be upon him) with the meat of a wild donkey as a gift, but he (peace and blessings be upon him) returned it. When he (peace and blessings be upon him) saw signs of displeasure on my face, he said: "We have not returned it for any reason other than that we are in the state of ihram."
He said that he was asked about the children of the polytheists, when their women and children are killed during a night raid, and he (peace and blessings be upon him) said: "They too are from among them."
He said: I heard him (peace and blessings be upon him) say: "There is no protected pasture except for Allah and His Messenger." Ali (may Allah have mercy on him) said: Sufyan (may Allah have mercy on him) said this twice during the gathering.
When Sufyan (may Allah have mercy on him) narrated this hadith, he would say: Ibn Ka'b bin Malik narrates from his uncle that when he (peace and blessings be upon him) sent them to Ibn Abi al-Huqayq, he forbade the killing of women and children.
