Pride and rebellion (Iblis)

وَلَقَدْ خَلَقْنَـٰكُمْ ثُمَّ صَوَّرْنَـٰكُمْ ثُمَّ قُلْنَا لِلْمَلَـٰٓئِكَةِ ٱسْجُدُوا۟ لِـَٔادَمَ فَسَجَدُوٓا۟ إِلَّآ إِبْلِيسَ لَمْ يَكُن مِّنَ ٱلسَّـٰجِدِينَ

And We have certainly created you, [O mankind], and given you [human] form. Then We said to the angels, "Prostrate to Adam"; so they prostrated, except for Iblees. He was not of those who prostrated.
