7:2
كِتَـٰبٌ أُنزِلَ إِلَيْكَ فَلَا يَكُن فِى صَدْرِكَ حَرَجٌ مِّنْهُ لِتُنذِرَ بِهِۦ وَذِكْرَىٰ لِلْمُؤْمِنِينَ
kitābun unzila ilayka falā yakun fī ṣadrika ḥarajun min'hu litundhira bihi wadhik'rā lil'mu'minīna
This Book has been sent down to you [Prophet]––let there be no anxiety in your heart because of it––so that you may use it to give warning and to remind the believers:
(This is the) Book (the Qur’ân) sent down unto you (O Muhammad صلى الله عليه وسلم), so let not your breast be narrow therefrom, that you warn thereby; and a reminder unto the believers.
