Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
How can we inspire people to long for the Messenger of Allah?
We can do this by mentioning his virtues, qualities and his life and by embodying his character and his dealings and by deepening our love, longing and veneration for him.
If such a person speaks he will have such an effect on those listening such that they will begin to long for the Messenger of Allah ﷺ.
