[Machine] I came to the Prophet ﷺ to pledge allegiance to him, but when I arrived, he had passed away, and Abu Bakr was standing in his place. He praised and cried for a long time, then he said, "I heard the Messenger of Allah ﷺ saying, 'Disbelief is to deny one's lineage, even if it is known, and to claim a lineage that is unknown.'"
أَتَيْتُ النَّبِيَّ ﷺ لِأُبَايِعَهُ فَجِئْتُ وَقَدْ قُبِضَ وَأَبُو بَكْرٍ قَائِمٌ فِي مَقَامِهِ فَأَطَالَ الثَّنَاءَ وَأَكْثَرَ الْبُكَاءَ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «كُفْرٌ بِاللَّهِ انْتِفَاءٌ مِنْ نَسَبٍ وَإِنْ دَقَّ وَادِّعَاءُ نَسَبٍ لَا يُعْرَفُ»
