Qur'an 7:2 · Al-A'raaf

كِتَٰبٌ أُنزِلَ إِلَيْكَ فَلَا يَكُن فِى صَدْرِكَ حَرَجٌۭ مِّنْهُ لِتُنذِرَ بِهِۦ وَذِكْرَىٰ لِلْمُؤْمِنِينَ

(2) [This is] a Book revealed to you, [O Muḥammad] - so let there not be in your breast distress therefrom - that you may warn thereby and as a reminder to the believers.
