Chapter 4, Verse 119, The Women
سورة النساء
وَلَأُضِلَّنَّهُمۡ وَلَأُمَنِّيَنَّهُمۡ وَلَأٓمُرَنَّهُمۡ فَلَيُبَتِّكُنَّ ءَاذَانَ ٱلۡأَنۡعَٰمِ وَلَأٓمُرَنَّهُمۡ فَلَيُغَيِّرُنَّ خَلۡقَ ٱللَّهِۚ وَمَن يَتَّخِذِ ٱلشَّيۡطَٰنَ وَلِيّٗا مِّن دُونِ ٱللَّهِ فَقَدۡ خَسِرَ خُسۡرَانٗا مُّبِينٗا
Verily, I will mislead them, and surely, I will arouse in them false desires; and certainly, I will order them to slit the ears of cattle, and indeed I will order them to change the nature created by Allah." And whoever takes Shaitan (Satan) as a Wali (protector or helper) instead of Allah, has surely suffered a manifest loss.
