question #1 Sahih Muslim 889, Book 8, Hadith 9 : What was the practice of the Prophet (ﷺ) regarding the sequence of prayer and announcements on the days of Eid?

Give alms, give alms, give alms, and the majority that gave alms was of women. He then returned and this (practice) remained (in vogue) till Marwan b. al- Hakam (came into power). I went out hand in hand with Marwan till we came to the place of worship and there Kathir b. Salt had built a pulpit of clay and brick. Marwan began to tug me with his hand as though he were pulling me towards the pulpit, while I was pulling him towards the prayer. When I saw him doing that I said: What has happened to the practice of beginning with prayer? He said: No, Abu Sa’id, what you are familiar with has been abandoned. I thereupon said (three times and went back): By no means, by Him in Whose hand my life is, you are not doing anything better than what I am familiar with.
