۞ وَقَالَ ٱلَّذِينَ لَا يَرْجُونَ لِقَآءَنَا لَوْلَآ أُنزِلَ عَلَيْنَا ٱلْمَلَٰٓئِكَةُ أَوْ نَرَىٰ رَبَّنَا ۗ لَقَدِ ٱسْتَكْبَرُوا۟ فِىٓ أَنفُسِهِمْ وَعَتَوْ عُتُوًّۭا كَبِيرًۭا
And those who look not for a meeting with Us say: Why are angels not sent down unto us and (Why) do we not see our Lord! Assuredly they think too highly of themselves and are scornful with great pride.
Surah Al-Furqaan(25:21)
