Satan's enmity and deception toward humanity

وَلَأُضِلَّنَّهُمْ وَلَأُمَنِّيَنَّهُمْ وَلَـَٔامُرَنَّهُمْ فَلَيُبَتِّكُنَّ ءَاذَانَ ٱلْأَنْعَـٰمِ وَلَـَٔامُرَنَّهُمْ فَلَيُغَيِّرُنَّ خَلْقَ ٱللَّهِ ۚ وَمَن يَتَّخِذِ ٱلشَّيْطَـٰنَ وَلِيًّا مِّن دُونِ ٱللَّهِ فَقَدْ خَسِرَ خُسْرَانًا مُّبِينًا

And I will mislead them, and I will arouse in them [sinful] desires, and I will command them so they will slit the ears of cattle, and I will command them so they will change the creation of Allāh." And whoever takes Satan as an ally instead of Allāh has certainly sustained a clear loss.
