وَهُوَ ٱلَّذِي فِي ٱلسَّمَآءِ إِلَٰهٞ وَفِي ٱلۡأَرۡضِ إِلَٰهٞۚ وَهُوَ ٱلۡحَكِيمُ ٱلۡعَلِيمُ ٨٤
English translation (Saheeh International)
And it is He [i.e., Allāh] who is [the only] deity in the heaven, and on the earth [the only] deity. And He is the Wise, the Knowing.
Brief commentary
He (may He be glorified) is the true deity in the heavens and the true deity on earth. And He is the Wise in His creation, decree and management, and Knower of the conditions of His servants. None of them are hidden from Him.
