I have observed in the last few months that during the Jumu'ah salah, I hear the imam recite surah al-ala quite frequently, nearly all of the time. The previous imam also did this. I wondered why this is, and I presume that this is based on ahadith?
Question: Is there a hadith about the recitation of surah al-ala in Jumu'ah salah?
If there is, please could you include details regarding the authenticity and chain of narration.
