﴿ وَإِنَّهُۥ فِىٓ أُمِّ ٱلْكِتَٰبِ لَدَيْنَا لَعَلِىٌّ حَكِيمٌ ﴾

“And, verily, [originating as it does] in the source, with Us, of all revelation, it is indeed sublime, full of wisdom.”

And it is indeed fixed in the Mother Book the source of all the scriptures namely the Preserved Tablet which is with Us ladaynā substitutes for fī ummi’l-kitābi ‘in the Mother Book’ and it is indeed exalted above all the scriptures that came before it wise containing excellent wisdoms.
