إِنَّ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِنَا وَٱسْتَكْبَرُوا۟ عَنْهَا لَا تُفَتَّحُ لَهُمْ أَبْوَٰبُ ٱلسَّمَآءِ وَلَا يَدْخُلُونَ ٱلْجَنَّةَ حَتَّىٰ يَلِجَ ٱلْجَمَلُ فِى سَمِّ ٱلْخِيَاطِ ۚ وَكَذَٰلِكَ نَجْزِى ٱلْمُجْرِمِينَ
Lo! they who deny Our revelations and scorn them, for them the gates of heaven will nor be opened not will they enter the Garden until the camel goeth through the needle's eye. Thus do We requite the guilty.
