Sahih Bukhari Volume 5, Book 64, Hadith 4329

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، عَنْ عَاصِمٍ، قَالَ سَمِعْتُ أَبَا عُثْمَانَ، قَالَ سَمِعْتُ سَعْدًا ـ وَهْوَ أَوَّلُ مَنْ رَمَى بِسَهْمٍ فِي سَبِيلِ اللَّهِ ـ وَأَبَا بَكْرَةَ ـ وَكَانَ تَسَوَّرَ حِصْنَ الطَّائِفِ فِي أُنَاسٍ ـ فَجَاءَ إِلَى النَّبِيِّ صلى الله عليه وسلم فَقَالاَ سَمِعْنَا النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏"‏ مَنِ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهْوَ يَعْلَمُ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ ‏"‏‏.‏ وَقَالَ هِشَامٌ وَأَخْبَرَنَا مَعْمَرٌ، عَنْ عَاصِمٍ، عَنْ أَبِي الْعَالِيَةِ، أَوْ أَبِي عُثْمَانَ النَّهْدِيِّ قَالَ سَمِعْتُ سَعْدًا، وَأَبَا، بَكْرَةَ عَنِ النَّبِيِّ صلى الله عليه وسلم‏.‏ قَالَ عَاصِمٌ قُلْتُ لَقَدْ شَهِدَ عِنْدَكَ رَجُلاَنِ حَسْبُكَ بِهِمَا‏.‏ قَالَ أَجَلْ أَمَّا أَحَدُهُمَا فَأَوَّلُ مَنْ رَمَى بِسَهْمٍ فِي سَبِيلِ اللَّهِ، وَأَمَّا الآخَرُ فَنَزَلَ إِلَى النَّبِيِّ صلى الله عليه وسلم ثَالِثَ ثَلاَثَةٍ وَعِشْرِينَ مِنَ الطَّائِفِ‏.‏

Narrated By Abu Uthman : I heard from Sad, 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 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 Ma'mar from 'Asim from Abu Al'Aliya or Abu Uthman An-Nahdi who said. "I heard Sad and Abu Bakra narrating from the Prophet." 'Asim 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 in a group of thirty-three persons from Ta'if.'
