﴿ وَمَا مِنْ غَآئِبَةٍۢ فِى ٱلسَّمَآءِ وَٱلْأَرْضِ إِلَّا فِى كِتَٰبٍۢ مُّبِينٍ ﴾

“for there is nothing [so deeply] hidden in the heavens or on earth but is recorded in [His] clear decree.”

And there is not a thing hidden in the heaven and the earth the hā’ tā’ marbūta of ghā’ibatun is hyperbole in other words anything that is completely hidden from people but it is in a manifest Book namely in the Preserved Tablet al-lawh al-mahfūz and in God’s concealed knowledge an example of which is the time of the chastising of the disbelievers.
