It was narrated that Simak bin Harb said: "I heard Jabir bin Samurah say: 'The Messenger of Allah ﷺ used to deliver the sermon standing, but he used to sit down briefly, then stand up.’"
The hadith also teaches us about balance and moderation in all aspects of life; even if we have certain routines or habits that we follow regularly, it is important to take breaks from them every once in a while so as not to become too rigid or stuck in one way of thinking. Taking breaks can help us gain perspective on things and allow us to come back with fresh ideas and energy.
