Acknowledge others even if you're busy or occupied with another task. Respond appropriately when being greeted by others even if you're busy or occupied with another task .

This hadith teaches us about proper etiquette when it comes to greeting someone who is in a state of urination. It is narrated that Ibn 'Umar said that a man passed by the Prophet while he was urinating and greeted him with salam, but the Prophet did not return his greeting. This shows us that it is disrespectful to greet someone who is in a state of urination, as it can be seen as an interruption or distraction from their task at hand. We should also be mindful of our own actions when we are in such a state, and refrain from engaging in conversation or other activities until we have finished our task. Furthermore, this hadith also teaches us about respect for others; even if someone greets us while we are engaged in something else, we should still take time to acknowledge them and respond appropriately.
