(Lo! those who disbelieve in the Reminder) i.e. the Qur'an (when it cometh unto them) when Muhammad (pbuh) took it to them; the reference here is to Abu Jahl and his host, ((are guilty)) and in the Hereafter they will have the Fire of Gehenna, (for lo! It) i. e. the Qur'an (is an unassailable Scripture) a glorious and noble Scripture.
