17:53
وَقُل لِّعِبَادِى يَقُولُوا۟ ٱلَّتِى هِىَ أَحْسَنُ ۚ إِنَّ ٱلشَّيْطَـٰنَ يَنزَغُ بَيْنَهُمْ ۚ إِنَّ ٱلشَّيْطَـٰنَ كَانَ لِلْإِنسَـٰنِ عَدُوًّا مُّبِينًا
waqul liʿibādī yaqūlū allatī hiya aḥsanu inna l-shayṭāna yanzaghu baynahum inna l-shayṭāna kāna lil'insāni ʿaduwwan mubīnan
[Prophet], tell My servants to say what is best. Satan sows discord among them: Satan is a sworn enemy of man.
And say to My slaves (i.e. the true believers of Islâmic Monotheism) that they should (only) say those words that are the best. (Because) Shaitân (Satan) verily, sows a state of conflict and disagreements among them. Surely, Shaitân (Satan) is to man a plain enemy.
