2:7
خَتَمَ ٱللَّهُ عَلَىٰ قُلُوبِ هِمْ وَ عَلَىٰ سَمْعِ هِمْ وَ عَلَىٰٓ أَبْصَٰرِ هِمْ غِشَٰوَةٌ وَ لَ هُمْ عَذَابٌ عَظِيمٌ
Allah has set a seal upon their hearts and upon their hearing, and over their vision is a veil. And for them is a great punishment.
36:65
ٱلْ يَوْمَ نَخْتِمُ عَلَىٰٓ أَفْوَٰهِ هِمْ وَ تُكَلِّمُ نَآ أَيْدِي هِمْ وَ تَشْهَدُ أَرْجُلُ هُم بِ مَا كَانُ وا۟ يَكْسِبُ ونَ
That Day, We will seal over their mouths, and their hands will speak to Us, and their feet will testify about what they used to earn.
42:24
أَمْ يَقُولُ ونَ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا فَ إِن يَشَإِ ٱللَّهُ يَخْتِمْ عَلَىٰ قَلْبِ كَ وَ يَمْحُ ٱللَّهُ ٱلْ بَٰطِلَ وَ يُحِقُّ ٱلْ حَقَّ بِ كَلِمَٰتِ هِۦٓ إِنَّ هُۥ عَلِيمٌۢ بِ ذَاتِ ٱل صُّدُورِ
Or do they say, "He has invented about Allah a lie"? But if Allah willed, He could seal over your heart. And Allah eliminates falsehood and establishes the truth by His words. Indeed, He is Knowing of that within the breasts.
45:23
أَ فَ رَءَيْ تَ مَنِ ٱتَّخَذَ إِلَٰهَ هُۥ هَوَىٰ هُ وَ أَضَلَّ هُ ٱللَّهُ عَلَىٰ عِلْمٍ وَ خَتَمَ عَلَىٰ سَمْعِ هِۦ وَ قَلْبِ هِۦ وَ جَعَلَ عَلَىٰ بَصَرِ هِۦ غِشَٰوَةً فَ مَن يَهْدِي هِ مِنۢ بَعْدِ ٱللَّهِ أَ فَ لَا تَذَكَّرُ ونَ
Have you seen he who has taken as his god his [own] desire, and Allah has sent him astray due to knowledge and has set a seal upon his hearing and his heart and put over his vision a veil? So who will guide him after Allah? Then will you not be reminded?
6:46
قُلْ أَ رَءَيْ تُمْ إِنْ أَخَذَ ٱللَّهُ سَمْعَ كُمْ وَ أَبْصَٰرَ كُمْ وَ خَتَمَ عَلَىٰ قُلُوبِ كُم مَّنْ إِلَٰهٌ غَيْرُ ٱللَّهِ يَأْتِي كُم بِ هِ ٱنظُرْ كَيْفَ نُصَرِّفُ ٱلْ ءَايَٰتِ ثُمَّ هُمْ يَصْدِفُ ونَ
Say, "Have you considered: if Allah should take away your hearing and your sight and set a seal upon your hearts, which deity other than Allah could bring them [back] to you?" Look how we diversify the verses; then they [still] turn away.
83:25
يُسْقَ وْنَ مِن رَّحِيقٍ مَّخْتُومٍ
They will be given to drink [pure] wine [which was] sealed.
