question #3 Sahih Muslim 878a, Book 7, Hadith 78 : What is the significance of reciting specific Surahs during ‘Id and Friday prayers in Islam?

” Glorify The name of Thy Lord, the Most High” (Surah lxxxvii.), and:” Has there come to thee the news of the overwhelming event” (lxxxviii.). And when the ‘Id and Jumu’a combined on a day he recited these two (surah) in both the prayers.
