Jabir b. ahadeeth reported that the Messenger of Allah (ﷺ) commanded us to observe fast on the day of Ashura and exhorted us to do it and was particular about it But when (fasting) in Ramadan was made obligatory, he hence forth neither commanded us nor forbade us, nor was he so particular about it.

Hadith Commentary:
Benefits and Issues:
The extent to which the Prophet sallallahu alayhi wa sallam encouraged, motivated, emphasized, and exhorted fasting before the obligation of Ramadan was not matched by the same degree of emphasis or exhortation afterward. However, in general, encouragement and urging toward fasting continued even after its obligation; its reward and merit were mentioned, and the Prophet sallallahu alayhi wa sallam himself continued to fast.
