سورة الزمر
فَٱعۡبُدُواْ مَا شِئۡتُم مِّن دُونِهِۦۗ قُلۡ إِنَّ ٱلۡخَٰسِرِينَ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ وَأَهۡلِيهِمۡ يَوۡمَ ٱلۡقِيَٰمَةِۗ أَلَا ذَٰلِكَ هُوَ ٱلۡخُسۡرَانُ ٱلۡمُبِينُ
So worship what you like besides Him. Say (O Muhammad ﷺ): "The losers are those who will lose themselves and their families on the Day of Resurrection. Verily, that will be a manifest loss!"

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.
