And prevention will be placed between them and what they desire, as (34:54)

Almuntakhab Fi Tafsir Alquran Alkarim

And now between right and wrong resides justice intervening between them and their wish of attaining faith now in order to escape the torment of the fire facing them but they cannot. This is exactly what had befallen their likes who were suspicious of the truth which they considered void for uncertainty

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(34:54) A barrier will be placed between them and what they desire, as was done with the likes of them before. Surely they were in a disquieting doubt. *76

And prevention will be placed between them and what they desire, as meaning

*76) As a matter of fact, no one adopts shirk and atheism and denial of the Hereafter by conviction, nor can he, for conviction comes from knowledge. And no one has the knowledge that there is no God, or that many others have a share in Divine authority, or that there should be no Hereafter. Thus, whoever has adopted these beliefs in the world, has raised a structure on mere conjecture, which has no basis except doubt and suspicion, and this suspicion has led him to sheer error. Consequently, they doubted God's existence, they doubted the truth of Tauhid, they doubted the coming of the Hereafter; so much so that they made this doubt their faith and did not listen to the Prophets and expended and wasted their whole lifetime indulging in a wrong creed and way of life.

And prevention will be placed between them and what they desire, as meaning in Urdu

اُس وقت جس چیز کی یہ تمنا کر رہے ہوں گے اس سے محروم کر دیے جائیں گے جس طرح اِن کے پیش رو ہم مشرب محروم ہو چکے ہوں گے یہ بڑے گمراہ کن شک میں پڑے ہوئے تھے
