فَإِنَّمَا يَسَّرۡنَٰهُ بِلِسَانِكَ لِتُبَشِّرَ بِهِ ٱلۡمُتَّقِينَ وَتُنذِرَ بِهِۦ قَوۡمٗا لُّدّٗا ٩٧
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.
Translation: Saheeh International (English)
Each word's meaning and sound
We have made this Qur’ān easy by revealing it in your own language, O Messenger, so that you may bring glad news to those who are mindful by fulfilling My instructions and avoiding My prohibitions, and so that you may warn a people who are harsh in disputing and stubborn in accepting the truth.
