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 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."

كِتَـٰبٌ فُصِّلَتْ ءَايَـٰتُهُۥ قُرْءَانًا عَرَبِيًّا لِّقَوْمٍ يَعْلَمُونَ
A Book whose verses have been detailed, an Arabic Qur'an for a people who know,
بَشِيرًا وَنَذِيرًا فَأَعْرَضَ أَكْثَرُهُمْ فَهُمْ لَا يَسْمَعُونَ
As a giver of good tidings and a warner; but most of them turn away, so they do not hear.
قُلْ إِنَّمَآ أَنَا۠ بَشَرٌ مِّثْلُكُمْ يُوحَىٰٓ إِلَىَّ أَنَّمَآ إِلَـٰهُكُمْ إِلَـٰهٌ وَٰحِدٌ فَٱسْتَقِيمُوٓا۟ إِلَيْهِ وَٱسْتَغْفِرُوهُ ۗ وَوَيْلٌ لِّلْمُشْرِكِينَ
Say, O [Muhammad], "I am only a man like you to whom it has been revealed that your god is but one God; so take a straight course to Him and seek His forgiveness." And woe to those who associate others with Allah -
ٱلَّذِينَ لَا يُؤْتُونَ ٱلزَّكَوٰةَ وَهُم بِٱلْـَٔاخِرَةِ هُمْ كَـٰفِرُونَ
Those who do not give zakah, and in the Hereafter they are disbelievers.
