(Muhammed) 47 : 29
أَمْ حَسِبَ الَّذِينَ فِي قُلُوبِهِمْ مَرَضٌ أَنْ لَنْ يُخْرِجَ اللَّهُ أَضْغَانَهُمْ
Or do those in whose hearts is disease reckon that Allah will never reveal their ill-wills?
This verse warns that however the hypocrites try to hide their envy and hatred towards the believers, Allah will reveal evil inner thoughts from this world itself. See explanation 40: 25; 41: 19-24; and 45: 28-29.
