Is it permissible to say "لا حول" (no might/power) on its own, based on what was mentioned on the website regarding the impermissibility of saying "لا حول الله" (no might/power of God)?

The phrase "لا حول" (there is no might/power) on its own does not convey a good meaning. It is considered idle talk, and while not forbidden, it distorts the meaning of "لا حول ولا قوة إلا بالله" (there is no might or power except with Allah).
