CHAPTER: OBSERVANCE OF SILENCE IN SERMON ON FRIDAY
Abu Huraira reported Allaah's Messenger (sallAllaahu alayhi wa sallam) as saying: If you (even) ask your companion to be quiet on Friday while the Imam is delivering the sermon, you have in fact talked irrelevance.
A hadith like this has been narrated by Abu Huraira by another chain of transmitters.
The same hadith has been narrated by Abu Huraira, but instead of the word laghauta the word laghita has been used. Abu Zinad (one of the narrators) says that laghita is the dialect of Abu Huraira, whereas it is laghauta.
