Al-Hijr 15:11

مَا نُنَزِّلُ الْمَلَائِكَةَ إِلَّا بِالْحَقِّ وَمَا كَانُوا إِذًا مُّنظَرِينَ

We do not send down the angels except with truth; and the disbelievers would not then be reprieved.

إِنَّا نَحْنُ نَزَّلْنَا الذِّكْرَ وَإِنَّا لَهُ لَحَافِظُونَ

كَذَٰلِكَ نَسْلُكُهُ فِي قُلُوبِ الْمُجْرِمِينَ

Thus do We insert denial into the hearts of the criminals.

لَا يُؤْمِنُونَ بِهِ ۖ وَقَدْ خَلَتْ سُنَّةُ الْأَوَّلِينَ

They will not believe in it, while there has already occurred the precedent of the former peoples.

وَلَوْ فَتَحْنَا عَلَيْهِم بَابًا مِّنَ السَّمَاءِ فَظَلُّوا فِيهِ يَعْرُجُونَ

And [even] if We opened to them a gate from the heaven and they continued therein to ascend,
