Offer Salam both when entering and leaving a gathering

This hadith from the Prophet Muhammad ﷺ teaches us the importance of offering salam when entering and leaving a gathering. It is important to greet those who are already present with respect and kindness, as this is an act of good manners that will be rewarded by Allah. Additionally, it shows that we care for others and value their presence in our lives. The Prophet ﷺ also taught us that both acts of greeting are equally important; neither one is more meritorious than the other. This hadith serves as a reminder for us to always be mindful of our manners when interacting with others, no matter what situation we find ourselves in.
