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

“A DIVINE WRIT has been bestowed from on high upon thee -and let there be no doubt about this in thy heart-in order that thou mayest warn [the erring] thereby, and [thus] admonish the believers:”

This is a Book that is revealed to you — addressing the Prophet s — so let there be no inhibition no constraint in your breast because of it to convey it — for fear that you might be called a liar — that you may warn thereby li-tundhira ‘that you may warn’ is semantically connected to unzila ‘is revealed’ that is to say ‘it is revealed for the purposes of warning’ and as a reminder for those who believe in it.
