SPEAK THAT WHICH IS BEST

Surah Al-Isra, Verse 53:

وَقُل لِّعِبَادِي يَقُولُوا الَّتِي هِيَ أَحْسَنُ إِنَّ الشَّيْطَانَ يَنزَغُ بَيْنَهُمْ إِنَّ الشَّيْطَانَ كَانَ لِلْإِنسَانِ عَدُوًّا مُّبِينًا

And say to My servants (that) they speak that which is best; surely the Shaitan sows dissensions among them; surely the Shaitan is an open enemy to man
