But as for those in whose hearts is disease, it has [only] (9:125)

﴿وَأَمَّا الَّذِينَ فِي قُلُوبِهِم مَّرَضٌ فَزَادَتْهُمْ رِجْسًا إِلَىٰ رِجْسِهِمْ وَمَاتُوا وَهُمْ كَافِرُونَ﴾
[ التوبة: 125]

9:125 But as for those in whose hearts is disease, it has [only] increased them in evil [in addition] to their evil. And they will have died while they are disbelievers.

As for the hypocrites, the revelation of the Qur’ān with its laws and stories increases them in sickness and wickedness because of their rejection of what is revealed, so that these deplorable characteristics become fixed in them; and the disease of their hearts increase with the revelation of the Qur’ān, because whenever something is revealed they are sceptical about it.

But as for those in whose hearts is a disease (of doubt, disbelief and hypocrisy), it will add suspicion and doubt to their suspicion, disbelief and doubt, and they die while they are disbelievers.
