Musnad Ahmad Hadith 20736

It is narrated from a Companion that once in Wadi al-Qura, the Prophet (peace be upon him) was riding his horse. A man from Banu Qain asked the Prophet (peace be upon him), "O Messenger of Allah, who are these people?" The Prophet (peace be upon him) replied, "They are those upon whom is wrath," and he pointed towards the Jews. He asked, "Then who are these?" He replied, "They are the misguided," and he pointed towards the Christians. And a man came to the Prophet (peace be upon him) and said, "Your such-and-such slave has been martyred." The Prophet (peace be upon him) said, "Rather, he is dragging his cloak in Hellfire; this is the punishment for the cloak he took by betraying from the spoils of war."
