On Protecting One's Thoughts from Evil

Answered by Sayyidi al-Ḥabīb `Umar bin Hafīẓ (may Allāh preserve him and benefit us by him).

How can we protect our thoughts and intellects from evil?

You can do this by directing them towards contemplating the majesty of Allāh and our journey unto Him, His bounties and His signs that are in His creation. Bestowing abundant peace and blessings on the Prophet Muḥammad (may Allah bless him and grant him peace) will help in this.
