(Al-Anfal) 8 : 50
وَلَوْ تَرَىٰ إِذْ يَتَوَفَّى الَّذِينَ كَفَرُوا ۙ الْمَلَائِكَةُ يَضْرِبُونَ وُجُوهَهُمْ وَأَدْبَارَهُمْ وَذُوقُوا عَذَابَ الْحَرِيقِ
And if you could see when Angels take the soul of those who disbelieved; they will be striking their faces and their backs and will be saying: "You taste the punishment of the Burning Fire".
The human devil hypocritical leaders of different organizations among and their blind followers are the real Kafirs as explained in verse 4: 150-151. See explanation 6: 93, 130 and 7: 37.
