Greet one another with respect & humility

This hadith teaches us about the importance of brotherhood between Muslims. It is not permissible for two Muslims to be estranged from each other for more than three nights, as this can lead to a breakdown in communication and understanding between them. Furthermore, it encourages us to greet one another first when we meet, as this shows humility and respect towards our fellow Muslim brothers and sisters. Additionally, it teaches us that whoever greets the other first will be better in Allah's eyes. This hadith emphasizes how important it is that we maintain good relationships with our fellow believers so that we can all benefit from each others' company and support.
