سنن أبي داود

This tradition has also been transmitted by Abu Hurairah through a different chain of narrators. This version dies not mention that the Prophet (ﷺ) said to Abu Bakr: Raise your voice a litte ; or he said to 'Umar: Lower your voice a little. But this version adds: (The Prophet (ﷺ) said:) I heard you, Bilal, (reciting) ; you were reciting partly from this surah and partly from that surah. He said: This is all good speech ; Allah has combined one part with the other; The Prophet (ﷺ) said: All of you were correct.
