13 Preface وَما ذَرَأَ لَكُم فِي الأَرضِ مُختَلِفًا أَلوانُهُ ۗ إِنَّ في ذٰلِكَ لَآيَةً لِقَومٍ يَذَّكَّرونَYusuf AliAnd the things on this earth which He has multiplied in varying colours (and qualities):1 verily in this is a sign for men who celebrate the praises of God (in gratitude).2Whose heart has not been moved by the glorious gradation of colours in the sunset clouds? The gradations are infinite, and it is only the eye of an artist that can express their collective beauty. They are but a type of the infinite variety and gradation of qualities in the spiritual sphere even in the little space of our own globe. The big things that can be measured and defined have been spoken of before. Here we have mention of the subtle nuances in the spiritual world which can only be perceived by men who are so high in spiritual insight that their only reaction is to “celebrate the praises of God” in gratitude for His infinite Mercies.Read again n. 2030 above, and see how subtly we are led up from the perception of the big to the perception of the subtle and delicate colours and qualities in the spiritual world.
