Translation for 6:59

۞ وَعِندَهُۥ مَفَاتِحُ ٱلۡغَيۡبِ لَا يَعۡلَمُهَآ إِلَّا هُوَۚ وَيَعۡلَمُ مَا فِي ٱلۡبَرِّ وَٱلۡبَحۡرِۚ وَمَا تَسۡقُطُ مِن وَرَقَةٍ إِلَّا يَعۡلَمُهَا وَلَا حَبَّةٖ فِي ظُلُمَٰتِ ٱلۡأَرۡضِ وَلَا رَطۡبٖ وَلَا يَابِسٍ إِلَّا فِي كِتَٰبٖ مُّبِينٖ ٥٩
With Him are the keys of the unseen—no one knows them except Him.1 And He knows what is in the land and sea. Not even a leaf falls without His knowledge, nor a grain in the darkness of the earth or anything—green or dry—but is ˹written˺ in a perfect Record.2
