Surah Al-Hijr, verse 7

مَّا تَسْبِقُ مِنْ أُمَّةٍ أَجَلَهَا وَمَا يَسْتَـْٔخِرُونَ ﴿٥﴾

No nation will precede its term, nor will they remain thereafter.

وَقَالُوا۟ يَـٰٓأَيُّهَا ٱلَّذِى نُزِّلَ عَلَيْهِ ٱلذِّكْرُ إِنَّكَ لَمَجْنُونٌۭ ﴿٦﴾

And they say, "O you upon whom the message has been sent down, indeed you are mad.

مَا نُنَزِّلُ ٱلْمَلَـٰٓئِكَةَ إِلَّا بِٱلْحَقِّ وَمَا كَانُوٓا۟ إِذًۭا مُّنظَرِينَ ﴿٨﴾

We do not send down the angels except with truth; and they [i.e., the disbelievers] would not then be reprieved.

إِنَّا نَحْنُ نَزَّلْنَا ٱلذِّكْرَ وَإِنَّا لَهُۥ لَحَـٰفِظُونَ ﴿٩﴾

Indeed, it is We who sent down the message [i.e., the Qur’ān], and indeed, We will be its guardian.
