19:97
فَإِنَّمَايَسَّرْنَٰهُبِلِسَانِكَلِتُبَشِّرَبِهِٱلْمُتَّقِينَوَتُنذِرَبِهِۦقَوْمًالُّدًّا٩٧
fa-innamā yassarnāhu bilisānika litubashira bihi l-mutaqīna watundhira bihi qawman luddan
So, [O Muḥammad], We have only made it [i.e., the Qur’ān] easy in your tongue [i.e., the Arabic language] that you may give good tidings thereby to the righteous and warn thereby a hostile people.(97)
