Greet others with salutations; Live life according to Islamic teachings; Show kindness and respect towards others; Be mindful of mortality.

This hadith teaches us about the power of greeting. It is narrated by Abu Hurairah that Prophet Muhammad said that whenever someone greets him, Allah returns his soul to his body in the grave and he returns their greeting. This shows us how powerful a simple gesture like a greeting can be. It is an act of kindness and respect which can bring joy even after death. We should always remember to greet each other with salutations as it brings peace and happiness not only for ourselves but also for those around us. Furthermore, this hadith also reminds us of our mortality as it speaks about returning souls to bodies in graves; we should use this reminder to live our lives according to Islamic teachings so we can attain eternal bliss in Jannah after death.
