Reach out and greet your Muslim brother after three days of absence

This hadith emphasizes the importance of greeting one's Muslim brother. It teaches us that we should not neglect our brothers in faith, even if we are busy or have disagreements with them. We must make an effort to reach out and greet them after three days of absence, as this will bring us both reward from Allah SWT. Even if the other person does not respond, we will still be absolved from any sin related to neglecting our brothers in faith. This hadith also highlights the importance of brotherhood among Muslims, as it is a great virtue that brings us closer together and strengthens our bond with each other in Islam.
