The Prophet, peace be upon him, said, “He is not one of us who does not show mercy to the young and does not recognize the right of the elderly among us.” (Abu Dawud and At-Tirmidhi)

 

We also know that the Prophet, peace be upon him, also taught us to give precedence to the elderly in serving and greeting. He also warned us against ignoring or looking down on them.

 

In conclusion, greeting the elders and giving preference to them over others is a good practice encouraged by the Prophet, peace be upon him.

 

Almighty Allah knows best.
