Exchange salutations with fellow believers after 3 days have passed

This hadith emphasizes the importance of greeting fellow believers. It teaches us that it is not permissible to stay away from another believer for more than three days as this can lead to a lack of connection between them. If we do meet and greet each other, we will both receive a reward in return. However, if one does not reply to the salutation given by another person, then the person who initiated it will be absolved from any sin that may have been caused by staying apart from each other. This hadith also encourages us to maintain strong relationships with our fellow believers and reminds us that even small acts such as exchanging salutations can bring great rewards in return.
