question #3 Sahih Muslim 677j, Book 5, Hadith 387 : What can be learned from the Prophet’s decision to abandon the Qunut after a period of time?

Anas reported that the Messenger of Allah (ﷺ) observed Qunut for one month invoking curse upon some tribes of Arabia (those who were responsible for the murders in Bi’r Ma’una and Raji’), but then abandoned it.
