تَنزِيلًا مِّمَّنْ خَلَقَ ٱلْأَرْضَ وَٱلسَّمَٰوَٰتِ ٱلْعُلَى
Commentary:
The verse gives the reason why revelation of the Quran will bring success to the Holy Prophet and his followers. It is that the Quran has been revealed by the Creator of heavens and earth i.e. the Source of all power, and that its teachings possess all those qualities and characteristics that go to make a people strong and powerful.
