Allah SWT says: فِى قُلُوبِهِمْ مَّرَضٌ فَزَادَهُمُ اللَّهُ مَرَضًا ۖ وَلَهُمْ عَذَابٌ أَلِيمٌۢ بِمَا كَانُوا يَكْذِبُونَ "In their hearts is disease, so Allah has increased their disease; and for them is a painful punishment because they [habitually] used to lie." (QS. Al-Baqara: Verse 10) * Via the Beautiful Qur'an https://goo.gl/QLwc8B
