Quran Al-Baqarah 2:208
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ ٱدۡخُلُواْ فِي ٱلسِّلۡمِ كَآفَّةٗ وَلَا تَتَّبِعُواْ خُطُوَٰتِ ٱلشَّيۡطَٰنِۚ إِنَّهُۥ لَكُمۡ عَدُوّٞ مُّبِينٞ ٢٠٨
Translation
O you who have believed, enter into Islām completely [and perfectly] and do not follow the footsteps of Satan. Indeed, he is to you a clear enemy.
