Some of them are praised, some are condemned, and some are neglected, as previously mentioned.

These outward names were given to them to veil the inward meanings and so that their inward could be known from their outward forms.

Know that this permanent duration—lasting as long as the Pre-eternal Ancient who brought it into being—is not days nor nights, nor night nor day. Its existence, symbolized by Occultation (Ghayba) and Manifestation (Zuhur), was detailed through the cycles of lifting the veil dark [veil] existing from sins and from the cycles of concealment within it. For when the veil is lifted from us, we see the symbolized Day. The cycles of those days and nights, existing from the cycles of unveiling and concealment, were detailed, varied, and divided into these days, hours, months, years, and times for reasons I will clarify to you—some of which will guide you, if Allah the Exalted wills, to the Straight Path.

It is that when Allah the Exalted brought the celestial and terrestrial universes into being, He set for each of them a limited boundary, a known time, lordly knowledges, and luminous spiritual existences.
