We, indeed We, it is We who have sent down the Reminder, and indeed it is We who will preserve it.
Translation endnotes
[15:9] The Quran is protected through an interlocking error-sensitive mathematical code. The emphasis in this short verse is unique; with its four references to God and his controllers, it makes it clear that it is not the humans who would protect it, but the One who revealed the message. The word zikr (reminder) establishes a link between the preservation of the Quran and its mathematical system, which is described with the grammatically feminine of the same word, zikra (74:31). See 9:127; 41:41-42.
