Qur'ān 7:2 · Al-A'raf (الأعراف)

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

[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.
