وَهُوَ ٱلَّذِى خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ بِٱلْحَقِّ ۖ وَيَوْمَ يَقُولُ كُن فَيَكُونُ ۚ قَوْلُهُ ٱلْحَقُّ ۚ وَلَهُ ٱلْمُلْكُ يَوْمَ يُنفَخُ فِى ٱلصُّورِ ۚ عَٰلِمُ ٱلْغَيْبِ وَٱلشَّهَٰدَةِ ۚ وَهُوَ ٱلْحَكِيمُ ٱلْخَبِيرُ
He it is Who created the heavens and the earth in truth. In the day when He saith: Be! it is. His Word is the Truth, and His will be the Sovereignty on the day when the trumpet is blown. Knower of the Invisible and the Visible, He is the Wise, the Aware.
