What is the ruling on using terms such as: "the healing answer," "I create an opportunity, an idea, or a solution," "magical performance," and "magical plan"?

The basic principle concerning things and words is permissibility unless there is evidence to prohibit them. The phrase "the comprehensive answer" does not appear to have anything preventing its use. Similarly, the phrase "create an opportunity" is permissible. The phrases "magical performance" or "magical plan" are also permissible, as their apparent meaning is to liken something to magic in its powerful effect. This simile is acceptable, as the Prophet, peace and blessings be upon him, described some eloquent speech as magic, meaning that it influences souls in the same way that magic captivates them. Thus, it is "magic" in the sense of a simile, not the unlawful magic.
