It is we who will collect it into Quran.
It's gathering and reciting is upon Us
Surely on Us rests the collecting of it and the reciting of it

Assuredly, upon Us rests its collection and preservation (in your breast) and its recitation (by your tongue)
The responsibility of its collection and its arrangement lies on Us
