فِي قُلُوبِهِم مَّرَضٌ فَزَادَهُمُ اللَّهُ مَرَضًا ۖ وَلَهُمْ عَذَابٌ أَلِيمٌ بِمَا كَانُوا يَكْذِبُونَ (10)
(2:10) In their hearts is a disease which Allah has increased all the more *12 and a painful doom is in store for them for the lie they utter.
*12). ' Disease' here refers to the disease of hypocrisy. The statement that 'Allah has intensified this disease' means that He does not punish the hypocrites immediately but allows them to indulge in their hypocrisy and exult in the success of their ruses. This feeling of success intensifies their hypocrisy.
