50 Preface أَفي قُلوبِهِم مَرَضٌ أَمِ ارتابوا أَم يَخافونَ أَن يَحيفَ اللَّهُ عَلَيهِم وَرَسولُهُ ۚ بَل أُولٰئِكَ هُمُ الظّالِمونَYusuf AliIs it that there is a disease in their hearts? or do they doubt, or are they in fear, that God and His Messenger will deal unjustly with them? Nay, it is they themselves who do wrong.1The real fact is that their conscience smites them. They know their own iniquity, and do not wish to go before a just judge who would be open to no influence and would be sure to give a righteous decree.
