40:70
ٱلَّذِينَ كَذَّبُوا۟ بِٱلْكِتَـٰبِ وَبِمَآ أَرْسَلْنَا بِهِۦ رُسُلَنَا ۖ فَسَوْفَ يَعْلَمُونَ
alladhīna kadhabū bil-kitābi wabimā arsalnā bihi rusulanā fasawfa yaʿlamūna
those who reject the Scripture and the messages We have sent through Our messengers? They will find out
Those who deny the Book (this Qur’ân), and that with which We sent Our Messengers (i.e. to worship none but Allâh Alone sincerely, and to reject all false deities and to confess resurrection after the death for recompense) they will come to know (when they will be cast into the Fire of Hell).
