(Fuswilath) 41 : 5
وَقَالُوا قُلُوبُنَا فِي أَكِنَّةٍ مِمَّا تَدْعُونَا إِلَيْهِ وَفِي آذَانِنَا وَقْرٌ وَمِنْ بَيْنِنَا وَبَيْنِكَ حِجَابٌ فَاعْمَلْ إِنَّنَا عَامِلُونَ
And they said: Our hearts are concealed to what you are calling us, and there is a lid in our ears also, and there is a barrier in between you and us, then you do in your way, while we are doing in our ways.
It is told in verses 17: 45-46 about Arabic Qur’an reading Fujjar that when they are made to hear the Clear manifest reading Adhikr, Allah will put a barrier between you and those who do not believe in the Hereafter. The verses 6: 25 and 18: 57 are also having the same Message. As told in verse 83: 15 there will be an unseen barrier in the Hereafter between the Lord of the universe and the Fujjar who don’t familiarise about the Lord to the mankind with the Three Time Knowledge Adhikr. See explanation 2: 165-167; 14: 9; 25: 29-30.
