Surah An-Nisa — Ayah 119 (4:119)
وَلَأُضِلَّنَّهُمۡ وَلَأُمَنِّيَنَّهُمۡ وَلَأٓمُرَنَّهُمۡ فَلَيُبَتِّكُنَّ ءَاذَانَ ٱلۡأَنۡعَٰمِ وَلَأٓمُرَنَّهُمۡ فَلَيُغَيِّرُنَّ خَلۡقَ ٱللَّهِۚ وَمَن يَتَّخِذِ ٱلشَّيۡطَٰنَ وَلِيّٗا مِّن دُونِ ٱللَّهِ فَقَدۡ خَسِرَ خُسۡرَانٗا مُّبِينٗا ١١٩
English translation (Saheeh International)
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.
Brief commentary
He also said: I will block them from your straight path. I will give them hopes with false promises that will make their misguidance seem attractive. I will instruct them to cut the ears of cattle, forbid that which Allah has made lawful, and change Allah’s creation and the natural disposition He made within all creatures. Whoever takes Satan as a friend to follow suffers a clear loss by doing so.
