Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
bayhaqi:4612 – Abū ʿAlī al-Rūdhbārī > Abū Bakr Muḥammad b. Bakr > Abū Dāwud > Aḥmad b. Saʿīd al-Hamadhānī > ʿAbdullāh b. Wahb > Muslim b. Khālid > al-ʿAlāʾ b. ʿAbd al-Raḥman from his father > Abū Hurayrah

The Messenger of Allah ﷺ came out and saw that the people were praying during (the night of) Ramadan in the corner of the mosque. He asked: Who are these people ? It was said to him that those were people who had not learnt Quran. But Ubayy b. Ka'b is praying and they would pray behind him. The Prophet ﷺ said: They did right and it is good what they did. Abu Dawud said: This tradition is not strong, the narrator Muslim b. Khalid is weak. (Using translation from Abū Dāʾūd 1377)   

البيهقي:٤٦١٢ – أنبأ أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنبأ أَبُو بَكْرٍ مُحَمَّدُ بْنُ بَكْرٍ ثنا أَبُو دَاوُدَ ثنا أَحْمَدُ بْنُ سَعِيدٍ الْهَمَذَانِيُّ ثنا عَبْدُ اللهِ بْنُ وَهْبٍ أَخْبَرَنِي مُسْلِمُ بْنُ خَالِدٍ عَنِ الْعَلَاءِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ قَالَ

خَرَجَ رَسُولُ اللهِ ﷺ فَإِذَا أُنَاسٌ فِي رَمَضَانَ يُصَلُّونَ فِي نَاحِيَةِ الْمَسْجِدِ فَقَالَ مَا هَؤُلَاءِ؟ فَقِيلَ هَؤُلَاءِ أُنَاسٌ لَيْسَ مَعَهُمْ قُرْآنٌ وَأُبَيُّ بْنُ كَعْبٍ يُصَلِّي وَهُمْ يُصَلُّونَ بِصَلَاتِهِ فَقَالَ النَّبِيُّ ﷺ أَصَابُوا وَنِعْمَ مَا صَنَعُوا قَالَ أَبُو دَاوُدَ هَذَا الْحَدِيثُ لَيْسَ بِالْقَوِيِّ مُسْلِمُ بْنُ خَالِدٍ ضَعِيفٌ
