I heard from Saʿd, the first man who has thrown an arrow in Allah's Cause, and from Abu Bakra who jumped over the wall of the Ta'if Fort along with a few persons and came to the Prophet. They both said, "We heard the Prophet ﷺ saying, " If somebody claims to be the son of somebody other than his father knowingly, he will be denied Paradise (i.e. he will not enter Paradise).' " Narrated Maʿmar from ʿAsim from Abu Al-ʿAliya or Abu ʿUthman An-Nahdi who said. "I heard Saʿd and Abu Bakra narrating from the Prophet." ʿAsim said, "I said (to him), 'Very trustworthy persons have narrated to you.' He said, 'Yes, one of them was the first to throw an arrow in Allah's Cause and the other came to the Prophet ﷺ in a group of thirty-three persons from Ta'if.'
