bayhaqi:12465Abū ʿAlī al-Rūdhbārī > Abū Bakr b. Dāsah > Abū Dāwud > Musaddad > ʿAbd al-Wārith > ʿAmr b. Abū Ḥakīm al-Wāsiṭī > ʿAbdullāh b. Buraydah > Akhawayn Ākhtaṣamā > Yaḥyá b. Yaʿmar Yahūdī And Muslim Fawarrath al-Muslim Minhumā > Abū al-Aswad > a man > Muʿādh

[Machine] I heard the Messenger of Allah ﷺ saying, "Islam increases and does not decrease, so the Muslim should inherit, and if the news is correct, its interpretation is other than what it went to. He only meant that Islam is in increase and does not decrease by apostasy." And this man is unknown, so he is cut off.  

البيهقي:١٢٤٦٥وَرَوَاهُ عَبْدُ الْوَارِثِ بْنُ سَعِيدٍ كَمَا أَخْبَرَنَا أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنا أَبُو بَكْرِ بْنُ دَاسَةَ ثنا أَبُو دَاوُدَ ثنا مُسَدَّدٌ ثنا عَبْدُ الْوَارِثِ عَنْ عَمْرِو بْنِ أَبِي حَكِيمٍ الْوَاسِطِيِّ ثنا عَبْدُ اللهِ بْنُ بُرَيْدَةَ أَنَّ أَخَوَيْنِ اخْتَصَمَا إِلَى يَحْيَى بْنِ يَعْمَرَ يَهُودِيٌّ وَمُسْلِمٌ فَوَرَّثَ الْمُسْلِمَ مِنْهُمَا وَقَالَ حَدَّثَنِي أَبُو الْأَسْوَدِ أَنَّ رَجُلًا حَدَّثَهُ أَنَّ مُعَاذًا قَالَ

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ الْإِسْلَامُ يَزِيدُ وَلَا يَنْقُصُ فَوَرَّثَ الْمُسْلِمَ وَإِنْ صَحَّ الْخَبَرُ فَتَأْوِيلُهُ غَيْرُ مَا ذَهَبَ إِلَيْهِ إِنَّمَا أَرَادَ أَنَّ الْإِسْلَامَ فِي زِيَادَةٍ وَلَا يَنْقُصُ بِالرِّدَّةِ وَهَذَا رَجُلٌ مَجْهُولٌ فَهُوَ مُنْقَطِعٌ
