English translation
4326, 4327. Narrated Abū 'Uthmān رضي الله عنه: I heard from Sa'd, (the first man who has thrown an arrow in Allāh's Cause), and from Abū Bakra (who jumped over the wall of Aṭ-Ṭā'if Fort along with a few persons and came to the Prophet ﷺ). 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 forbidden to (enter) Paradise (i.e., Paradise will be illegal for him i.e., he will not enter Paradise).'" Narrated Ma'mar from 'Aṣim from Abū Al-'Āliya or Abū 'Uthmān An-Nahdi who said, "I heard Sa'd and Abū Bakra narrating on the authority of the Prophet ﷺ. 'Aṣim said, "I said (to him), 'The most trustworthy persons have narrated that to you.' He said, 'Yes, one of them was the first to throw an arrow in Allāh's Cause and the other came to the Prophet ﷺ in a group as the third of the twenty-three persons from Aṭ-Ṭā'if.'"
