Surah Fussilat 41:5

وَقَالُوا۟ قُلُوبُنَا فِىٓ أَكِنَّةٍ مِّمَّا تَدْعُونَآ إِلَيْهِ وَفِىٓ ءَاذَانِنَا وَقْرٌ وَمِنۢ بَيْنِنَا وَبَيْنِكَ حِجَابٌ فَٱعْمَلْ إِنَّنَا عَـٰمِلُونَ

And they say, "Our hearts are within coverings [i.e., screened] from that to which you invite us, and in our ears is deafness, and between us and you is a partition, so work; indeed, we are working."

Translation: Saheeh International
