كِتٰبٌ اُنْزِلَ اِلَيْكَ فَلَا يَكُنْ فِيْ صَدْرِكَ حَرَجٌ مِّنْهُ لِتُنْذِرَ بِهٖ وَذِكْرٰى لِلْمُؤْمِنِيْنَ
Kitābun unzila ilaika falā yakun fī ṣadrika ḥarajum minhu litunżira bihī wa żikrā lil-mu'minīn(a).
"[This is] a Book revealed to you, [O Muhammad] - so let there not be in your breast distress therefrom - that you may warn thereby and as a reminder to the believers."
