2. The revelation of the Book is from Allah the Exalted in Power Full of Wisdom.

Notes (Tafseer)

4775. This verse is the same as the second verse of the last Sura, but the theme is worked out differently in the two Sura. In S. xlv. was shown how deniers of Revelation will at last be humbled until they can no longer deny its truth and power. In this Sura is shown how Truth and Revelation will be vindicated by patience and constancy (xlvi. 35).
