4204. Narrated Abū Hurairah رضي الله عنه: We witnessed (the battle of) Khaibar. Allāh's Messenger ﷺ said about one of those who were with him and who claimed to be a Muslim. "This (man) is from the dwellers of the Hell-fire." When the battle started, that fellow fought so violently and bravely that he received plenty of wounds. Some of the people were about to doubt (the Prophet's statement), but the man, feeling the pain of his wounds, put his hand into his quiver and took out of it some arrows with which he slaughtered himself (committed suicide). Then some men amongst the Muslims came hurriedly and said, "O Allāh's Messenger! Allāh has made your statement true; so-and-so has committed suicide." The Prophet ﷺ said, "O so-and-so! Stand up and make an announcement that none will enter Paradise but a believer and that Allāh may support the religion (Islām) with a Fājir [a wicked (sinful)] man."
