Fussilat, 5 Ayah
41:5
وَقَالُواْ قُلُوبُنَا فِيٓ أَكِنَّةٖ مِّمَّا تَدۡعُونَآ إِلَيۡهِ وَفِيٓ ءَاذَانِنَا وَقۡرٞ وَمِنۢ بَيۡنِنَا وَبَيۡنِكَ حِجَابٞ فَٱعۡمَلۡ إِنَّنَا عَٰمِلُونَ ٥
Wa Qālū Qulūbunā Fī 'Akinnatin Mimmā Tad`ūnā 'Ilayhi Wa Fī 'Ādhāninā Waqrun Wa Min Bayninā Wa Baynika Ĥijābun Fā`mal 'Innanā `Āmilūna
And they say, "Our hearts are within coverings 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."
