Narrated Abu Hurairah: 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 bin Kab 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 bin Khalid is weak.
