Quran 19:97 from Surah Maryam on Divine Marvels.
فَإِنَّمَا يَسَّرۡنَٰهُ بِلِسَانِكَ لِتُبَشِّرَ بِهِ ٱلۡمُتَّقِينَ وَتُنذِرَ بِهِۦ قَوۡمٗا لُّدّٗا
English translation: So only We (have) made it easy in your tongue that you may give glad tidings with it (to) the righteous and warn with it a people hostile
Transliteration: fa-innama yassarnahu bilisanika litubashira bihi al-mutaqina watundhira bihi qawman luddan
