For Him (alone) is prayer in Truth: any others that they call upon besides Him hear them no more than if they were to stretch forth their hands for water to reach their mouths but it reaches them not: for the prayer of those without Faith is nothing but (futile) wandering (in the mind).
Haq: truth; right; what is due, befitting, proper.
All these meanings are to be understood here.
If we worship anything other than Allah (whether it is
idols, stars, powers of nature, spirits, or deified men, or
Self, or Power, or Wealth, Science or Art, Talent or
Intellect), our worship is both foolish and futile.
