Answered by Sayyidi al-Ḥabīb `Umar bin Hafīẓ (may Allāh preserve him and benefit us by him).
How we do motivate people to attend gatherings of remembrance?
This can be achieved by reminding them of the merits of the remembrance of Allāh that are mentioned in the Qur’ān and Sunnah. Also you must seek to experience the meaning of remembrance so that you carry the desire to the one who you are speaking to. This is attained through your heart being attached through your chain of connection to the Prophet Muḥammad and striving to attain brokenness and humbleness in front of Allāh.
