أُوْلَٰٓئِكَ ٱلَّذِينَ طَبَعَ ٱللَّهُ عَلَىٰ قُلُوبِهِمۡ وَسَمۡعِهِمۡ وَأَبۡصَٰرِهِمۡۖ وَأُوْلَٰٓئِكَ هُمُ ٱلۡغَٰفِلُونَ ١٠٨
Those are the ones over whose hearts and hearing and vision Allāh has sealed, and it is those who are the heedless.
Translation: Saheeh International (English)
Each word's meaning and sound
Those described as being apostates after having faith are the ones whose hearts Allah has sealed, so they do not understand the admonition, He has sealed their hearing, so that they do not hear anything that benefits them, and He has sealed their sight, so that they do not see the signs indicating faith. It is they who are unaware of the causes of happiness and wretchedness and of the punishment that Allah has prepared for them.
