It is in conformity with the requirements of the situation, which is the definition of eloquence and its basis.1 And it is free of exaggeration, which is wastefulness in words.
It is clear that the person will be wretched who does not take refuge in a secure stronghold in the face of terrible enemies who wreak much destruction with little action. O people of belief! Such a heavenly stronghold of steel is the Qur’an. Enter it and be saved!
Investigative scholars and the people of illumination have agreed that non-existence is pure evil and existence, pure good. Yes, in the great majority of cases, good, virtues, and perfections are based on existence and are related to it.

Such things may be the cause of something non-existent.
