﴿ إِنَّ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِنَا وَٱسْتَكْبَرُوا۟ عَنْهَا لَا تُفَتَّحُ لَهُمْ أَبْوَٰبُ ٱلسَّمَآءِ وَلَا يَدْخُلُونَ ٱلْجَنَّةَ حَتَّىٰ يَلِجَ ٱلْجَمَلُ فِى سَمِّ ٱلْخِيَاطِ ۚ وَكَذَٰلِكَ نَجْزِى ٱلْمُجْرِمِينَ ﴾

“VERILY, unto those who give the lie to Our messages and scorn them in their pride, the gates of heaven shall not be opened; and they shall not enter paradise any more than a twisted rope can pass through a needle's eye: for thus do We requite such as are lost in sin.”

Those who deny Our signs and scorn them not believing in them indeed the gates of heaven shall not be opened for them when their spirits are carried up to it after death for instead they are taken down into Sijjīn cf. Q. 837f. — in contrast to the believer for whom the gates are opened and his spirit is carried up into the seventh heaven as is stated in one hadīth — nor shall they enter Paradise until the camel passes through the eye of the needle which is impossible and so is their entry into Paradise. So with this requital We requite those who are sinful through disbelief.
