Abu Salama b. Abd al-Rabman reported:
'Abd al-Rabman b. Abu Sa'id al-Khudri (Allah be pleased with him) happened to pass by me and I said to him. How did you hear your father making mention of the mosque founded on Piety? He said: My father said: I went to Allah's Messenger (ﷺ) as he was in the house of one of his wives, and said: Messenger of Allah, which of the two mosques is founded on piety? Thereupon he took a handful of pebbles and threw them on the ground and then said: This is the very mosque of yours (mosque at Medina). He (the narrator) said: I bear witness that I heard your father making mention of it.
حَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ حُمَيْدٍ الْخَرَّاطِ، قَالَ سَمِعْتُ أَبَا سَلَمَةَ بْنَ عَبْدِ الرَّحْمَنِ، قَالَ مَرَّ بِي عَبْدُ الرَّحْمَنِ بْنُ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ قُلْتُ لَهُ كَيْفَ سَمِعْتَ أَبَاكَ يَذْكُرُ فِي الْمَسْجِدِ الَّذِي أُسِّسَ عَلَى التَّقْوَى قَالَ قَالَ أَبِي دَخَلْتُ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فِي بَيْتِ بَعْضِ نِسَائِهِ فَقُلْتُ يَا رَسُولَ اللَّهِ أَىُّ الْمَسْجِدَيْنِ الَّذِي أُسِّسَ عَلَى التَّقْوَى قَالَ فَأَخَذَ كَفًّا مِنْ حَصْبَاءَ فَضَرَبَ بِهِ الأَرْضَ ثُمَّ قَالَ
" هُوَ مَسْجِدُكُمْ هَذَا "
. - لِمَسْجِدِ الْمَدِينَةِ - قَالَ فَقُلْتُ أَشْهَدُ أَنِّي سَمِعْتُ أَبَاكَ هَكَذَا يَذْكُرُهُ .
Abu Sa'id reported from Allah's Apostle (ﷺ) a hadlth like this, but in the chain of transmitters no mention was made of Abd al- Rahman b. Abu Sa'id.
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَسَعِيدُ بْنُ عَمْرٍو الأَشْعَثِيُّ، قَالَ سَعِيدٌ أَخْبَرَنَا وَقَالَ أَبُو بَكْرٍ، حَدَّثَنَا حَاتِمُ بْنُ إِسْمَاعِيلَ، عَنْ حُمَيْدٍ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي سَعِيدٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِمِثْلِهِ وَلَمْ يَذْكُرْ عَبْدَ الرَّحْمَنِ بْنَ أَبِي سَعِيدٍ فِي الإِسْنَادِ .
