ibnhibban:2541 – Muḥammad b. Isḥāq b. Khuzaymah > al-Rabīʿ b. Sulaymān > Ibn Wahb > Muslim b. Khālid > al-ʿAlāʾ 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)   

ابن حبّان:٢٥٤١ – أَخْبَرَنَا مُحَمَّدُ بْنُ إِسْحَاقَ بْنِ خُزَيْمَةَ قَالَ حَدَّثَنَا الرَّبِيعُ بْنُ سُلَيْمَانَ قَالَ حَدَّثَنَا ابْنُ وَهْبٍ قَالَ أَخْبَرَنَا مُسْلِمُ بْنُ خَالِدٍ عَنِ الْعَلَاءِ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ قَالَ

خَرَجَ رَسُولُ اللَّهِ ﷺ فَإِذَا النَّاسُ فِي رَمَضَانَ يُصَلُّونَ فِي نَاحِيَةِ الْمَسْجِدِ فَقَالَ ﷺ «مَا هَؤُلَاءِ؟ » فَقِيلَ نَاسٌ لَيْسَ مَعَهُمْ قُرْآنٌ وَأُبَيُّ بْنُ كَعْبٍ يُصَلِّي بِهِمْ وَهُمْ يُصَلُّونَ بِصَلَاتِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ «أَصَابُوا أَوْ نِعْمَ مَا صَنَعُوا»
