وَحِيلَ بَيْنَهُمْ وَبَيْنَ مَا يَشْتَهُونَ كَمَا فُعِلَ بِأَشْيَاعِهِم مِّن قَبْلُ ۚ إِنَّهُمْ كَانُوا۟ فِى شَكٍّ مُّرِيبٍۭ
And prevention will be placed between them and what they desire, as was done with their kind before. Indeed, they were in disquieting denial.
Nearby ayahs help place verse 34:54 in sequence and meaning.
وَقَالُوٓا۟ ءَامَنَّا بِهِۦ وَأَنَّىٰ لَهُمُ ٱلتَّنَاوُشُ مِن مَّكَانٍۭ بَعِيدٍ
And they will [then] say, "We believe in it!" But how for them will be the taking [of faith] from a place far away?
وَقَدْ كَفَرُوا۟ بِهِۦ مِن قَبْلُ ۖ وَيَقْذِفُونَ بِٱلْغَيْبِ مِن مَّكَانٍۭ بَعِيدٍ
And they had already disbelieved in it before and would assault the unseen from a place far away.
