حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلَاءِ ، حَدَّثَنَا إِسْحَاق بْنُ مَنْصُورٍ السَّلُولِيُّ ، عَنْ جَعْفَرٍ الْأَحْمَرِ ، عَنْ السَّرِيِّ بْنِ إِسْمَاعِيل ، عَنْ قَيْسِ بْنِ أَبِي حَازِمٍ ، قَالَ : أَتَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِأُبَايِعَهُ، فَجِئْتُ وَقَدْ قُبِض، وَأَبُو بَكْرٍ قَائِمٌ فِي مَقَامِهِ، فَأَطَالَ الثَّنَاءَ وَأَكْثَرَ الْبُكَاءَ، فَقَالَ : سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، يَقُولُ :" كُفْرٌ بِاللَّهِ انْتِفَاءٌ مِنْ نَسَبٍ وَإِنْ دَقَّ، وَادِّعَاءُ نَسَبٍ لَا يُعْرَفُ "

Muhammad bin Al-Ala’ narrated to us, Ishaq bin Mansour Al-Saluli narrated to us, on the authority of Ja’far Al-Ahmar, on the authority of Al-Sari bin Ismail, on the authority of Qais bin Abi Hazim, he said: I came to the Prophet, may God bless him and grant him peace, to pledge allegiance to him, and I came and he had been arrested, and Abu Bakr was standing in his place, so he prolonged the praise. He cried more and said: I heard the Messenger of God, may God bless him and grant him peace, saying: “Disbelief in God is the absence of a lineage, even if it is accurate, and the claim of a lineage.” "It is not known"
