Thus, anxiety and sorrow do the servant no good at all; rather, their harm exceeds their benefit. They weaken resolve, sap the heart’s strength, and prevent the servant from striving for what benefits him. They cut off his path forward, turn him back, impede him and bring him to a halt, or (1) obscure the guiding landmark whose sight always spurs him to press towards it and pursue his journey earnestly.

There is no way to free the heart from these pains, which are its gravest and most destructive diseases, except through this. And there is no reaching this goal except through Allah alone, for none but He can bring one to Him, and no one brings
