Surah Al-Isra, ayah 53

وَقُل لِّعِبَادِي يَقُولُواْ ٱلَّتِي هِيَ أَحۡسَنُۚ إِنَّ ٱلشَّيۡطَٰنَ يَنزَغُ بَيۡنَهُمۡۚ إِنَّ ٱلشَّيۡطَٰنَ كَانَ لِلۡإِنسَٰنِ عَدُوّٗا مُّبِينٗا ٥٣

Waqul li'ibādī yaqūlul-latī hiya ahsanu innash-shaytāna yanzaghu baynahum innash-shaytāna kāna lil-insāni 'aduwwam mubīnā

And tell My servants to say that which is best. Indeed, Satan induces [dissension] among them. Indeed Satan is ever, to mankind, a clear enemy.
