Al A’raf Ayah 2

كِتَـٰبٌ أُنزِلَ إِلَيْكَ فَلَا يَكُن فِى صَدْرِكَ حَرَجٌ مِّنْهُ لِتُنذِرَ بِهِۦ وَذِكْرَىٰ لِلْمُؤْمِنِينَ ٢ ?This is? a Book sent down to you ?O Prophet?—do not let anxiety into your heart regarding it—so with it you may warn ?the disbelievers?, and as a reminder to the believers.
