Narrated 'Aisha the mother of the faithful believers: One night Allah's Messenger ﷺ offered the prayer in the Mosque and the people followed him. The next night he also offered the prayer and too many people gathered. On the third and the fourth nights more people gathered, but Allah's Messenger ﷺ did not come out to them. In the morning he said, "I saw what you were doing and nothing but the fear that it (ie the prayer) might be enjoined on you, stopped me from coming to you". And that happened in the month of Ramadan.
The Prophet's fear of obligation also shows his mercy towards his followers; he wanted to make sure they were able to practice their faith without feeling overwhelmed or burdened by too many obligations. It also serves as a reminder for all of us not to take on more than we can handle when it comes to religious practices or any other aspect of life; instead, we should strive for balance and moderation so that our faith remains strong but manageable at the same time.
