Among the greatest cures to nervous and mental disorders, and even other illnesses of the body, is the firmness of the heart and its strength and lack of its being troubled and perturbed by illusions and imaginations brought about by evil thoughts.
There was a discussion about the issue of putting one’s trust in Allah (tawakkul) and taking measures; the trust of some of the righteous is like that of Maryam, to whom summer fruits used to come in the winter and vice versa without her taking any measures; rather she focused completely on worship. Please advise us about that, may Allah bless you.
You must have had those moments when you felt so strong, thinking: whatever needs to happen will happen. That sweet feeling of trusting in Allaah subhanahu wa ta’alaa is priceless, granting an amazing peace of mind.
Then there are the times you get tense. You worry. You feel a knot in your stomach. What if things just don’t get better? What if I lose him or her? What if I get ill?
